How do you go from an egg laying animal to producing live young? That’s not gonna happen they’re just going to keep producing eggs because that’s how they reproduce! Did they go from laying eggs to 1 day a mammal was born from a non mammal? Because how else would that process look like? How do you go from a non mammal to a mammal? Because if you have a non mammal slowly evolving to a mammal it’s just gonna die. If it somehow slowly evolved to a mammal from a non-mammal then what percentage does it birth live young and what percentage does it lay eggs? And how would that percentage work? You need to demonstrate it’s possible for an egg layer to slowly evolve to birth live young because that doesn’t make sense at all. How would that slowly change over time? There’s never been a single observed case of a genetic mutation which has actually been beneficial.

Evolution intuitively seems iffy to me as well.
Has there been any mathematical models to show the efficacy of it? Meaning that of random mutations then spreading, and having enough such mutations that successfully spread to create new species over the time scales discussed?
And I also don't understand how the situation you described would work.

Egg spent less and less time outside the mother as the shell got thinner and thinner. It all happened gradually. This would also be beneficial as an egg can be eaten, whereas a mother or newborn can run away from predators. So there is selection pressure and a path from egg to no egg.

It's just a theory. No one truly knows. Any theory no proven expirementally should be taken with a grain of salt.
Instead they indoctrinate the masses with evolution as implicit truth.
There is evidence of evolution but the expressed evolutionary genes are very tiny.
For example the sounds or colors or techniques that the species uses. The species itself stays the same.

Selection rules are irrelevant because one reaches the optimal fit where further variation is negative. Further adaptation requires drivers which is even more spaced out.

One day, the egg accidentally stayed inside and hatched there and the baby then fell out or was pushed out. This had the benefit of not exposing the baby to threats while it was in the egg.
After holding the egg inside became the norm, then one day the mother accidentally created a thin membrane instead of a thick egg shell. This had the benefit of allowing nutrients to pass through the membrane, enhancing the health of the baby and reducing the need to produce the yolk.
Eventually, the egg became the placenta.

You just keep the eggs inside you, hatch them internally, and then give live birth. Sharks, snakes, and a handful of other reptiles already do this.
From there the womb eventually expands, the egg stops developing a shell (don't need it) turning into an amniotic sac, and then you have a more conventional live birth. Marsupials are the in-between or compromise of this process in that they don't really build up a placenta and just give birth to a tiny jellybean into their pouch that they raise with meticulous care.

There have been mathematical models but it doesn't matter because we have something even better: Scientists have observed evolution happening live on species of fruit flies that have very short lifespans. It's not up for debate.

There are lizards that have both egg-laying and live-bearing individuals within a single species. Live bearing to egg laying isn’t a huge jump, reptile lineages in particular can swap back and forth

true, that is why every animal on our planet is producing eggs.
When women is ovulating her ovaries are releasing an ovum (a human egg cell) which is a human egg. (yeah it is an egg in the same way chicken eggs are eggs)
only difference is that in mammals egg stays and develops inside the woman until it hatches while in birds, fish, reptiles and amphibians lay fertilized eggs outside to develop and hatch there.

also eggs are not unique for animals either, plants have egg cells and sperm cells as well (funny thing is that plant sperm cells usually have multiple tails and sometimes swim backwards)

Or if you are a retarded vegan friendly cuck.
but you are obviously wrong mister, plants do have sperm cells (actually produced by pollen) and egg cells, they do need to meet in an act of "pollination" to be able to create a fertilized egg we call a seed.

>My problem with evolution
I sounds like you have a problem with macroevolution, not evolution as a whole. But I'll try to answer you since this is one of the most interesting problems in evolutionary biology.
>How do you go from an egg laying animal to producing live young?
At some point in time, a population of animals, for whatever reason, began hatching its eggs internally instead of laying the eggs.
Obviously, we cannot go back in time, nor do we know with 100% certainty what happened, but current mammals give us some hints:
Monotremes are mammals that lay eggs. The platypus and the four species of echidnas still lay eggs. This suggests that of the many mammalian features, live birthing was a late evolutionary step.
Next we have marsupials. Those animals give birth to a barely formed embryo, which crawls it way into the mother's pouch once born, and finishes there, externally to the mother's body, its gestation process. This suggests that the next step was for monotremes to hatch the eggs internally, and giving birth to vulnerable embryos, which in turn promoted the "pouch" adaptation to safeguard the wellbeing of the embryos and not leave them exposed.
From there, modern mammals evolved, with more developed newborns being born, and skipping the previous process altogether.

We don't know the exact sequence, we were not there, and the fossil record is like an eroded, tattered old book with lots of missing and degraded pages, but yes, one day, in a sufficiently reproductively isolated group of animals, a female animal was born either with a new mutation, or a novel combination of genes, which allowed her to not lay an egg. That female, though different from the other females, did not differ enough from the other population animals to the point where she could not reproduce with the males. In that way, she copulated with at least one male, and her offspring carried those genetic traits. Her offspring themselves might have also not laid eggs, and that genetic variant survived until today. It might have not have been reproductively advantageous, it might have just been passed onwards through Genetic Drift (randomness with no clear advantage), but it survived until today (primitive marsupials)

That is not true, you're literally describing microevolution, which happens everyday, everywhere.

You also need to understand that the mutation, or combination of already existing genes, might not have originated in that female. It might have originated in her father, and only have been expressed phenotypically in her, but the point is that indeed, one first female must have been born with such a trait, a female which then reproduced and passed those traits onto their offspring.

It generally doesn't change slowly over time. This is one of the most misunderstood parts of evolution, by both evolutionists and non-evolutionists. Evolution (read: autopoietic systems) optimizes for a very stable niche and then does not change frequently at all. Autopoietic systems tend to NOT change once they have optimized.
What actually causes the kind of significant evolution we are used to seeing are cases where populations reach extremely small counts by virtue of natural disasters, rapid ecological change, or introduction of new species. In these cases, genetic changes occurring in species will spread very rapidly through the entire population due to almost mandatory near- or distant-relative incest, and co-occur, causing rapid changes in behavior and morphology.
"Slow" in this case should be understood as a period as low as a few centuries. For example, for live births, consider a species which lay eggs that incubate to hatch. There is some period of time between when the egg is fertilized and when it is laid. In a situation where total species count suddenly drops and the species is exposed to predation against eggs, there is now enormous pressure to reduce the amount of time eggs can be predated. Members of the species that incubate eggs for a longer and longer time will tend to outlive those who do not. These genes proliferate rapidly, and over a few cycles the species may reach a point where eggs are laid with viable offspring inside them, and at that point there's no longer an advantage for laying the egg at all. We can see then how easily the line tips over to simply laying live offspring instead of forming a dense outer shell to protect the newborn.

Okay, now prove that these shifts will not revert back to what it was previously. Evolution means that you change from A to B irrevocably, not that you develop A+ form different food, unless you mean that obese people are an evolved homo sapiens
