Yeah I find it really ridiculous that you guys think that evolution is numero uno without a doubt.
The earth cannot grow to be anywhere near a billion years old.
Humans are not evolving as we speak, there is no evidence that they ever have, as far as I'm concerned they have never evolved, or atleast to the extent that you are suggesting.
Sure our morals, thoughts, and ways of life have changed over many years; but not our physical body structure.
A human cell, and an animal's cell can look alike, but they are not the same.
I once read of a bug or a spider, (I don't quite remember what exactly it was) some kind of creature.
That had a mechanism inside it that functioned for digestion or something.
And this mechanism had chemical-like substances that could basically be a bomb.
But it was also equipped with something else that stopped this destructive mechanism from completely exploding itself.
Now, if evolution were a thing, you would probably be saying that this spider died a not so nice death, thousands of times, until it developed the ability to contain the explosive power of this function which it uses to devour it's meals.
I feel like there are more points I was thinking of when I started writing this, but have forgotten at the moment.
So I don't know about religions or specific theories being true.
But the question of Evolution being, "The most probable", to be honest, makes me laugh.
