"How did evolution create gravity"
I don't know where gravity comes from. Neither do you.
"and make it the perfect balance so we don't float away or be so strong that we are crushed?"
What do you mean "perfect balance"? Gravity varies extremely depending on where you are in the universe - on some planets you would be crushed to death on others you'd float away. And by the way life is more or less unaffected by gravity, which is why we don't instantly die when we go into outer space. Your feet are being pulled on by gravity stronger than your head is right now (assuming you're not reading this upside down). The idea that there's some precise amount of gravity that won't kill us just isn't accurate. Go to the top of a mountain and you weigh less. And there is "life" that thrives at the bottom of the ocean under a thousand times the atmospheric pressure we're under. The earth isn't "fine tuned" to life, individual species are "fine-tuned" to the environment.
"Also, how do evolutionists explain instinct and/or adaption? They are such simple words for something that is so amazingly complex, it truly boggles the mind."
You are literally saying "I have absolutely no idea what evolution even is". Do you actually want to know the answer to this question or are you just trying to evangelize?
"Evolution does indeed exclude God."
In no way. Darwin believed in a god, as do most people in the US who accept evolution.
"Atheists believe in evolution, evolution excludes God. Granted, theistic evolutionists believe in God but that’s not for appropriate for this topic."
I don't see why not. And atheists tend to accept evolution not because it's atheistic but because they have no reason not to. Atheists also accept that the earth is round more often than christians (some fundamentalists argue it's flat and unmoving). That doesn't make the idea that the earth is round atheistic.
I see no reason to think a god couldn't create life that evolves as easily as creating life that doesn't. If anything it would be more impressive and "intelligently designed".
That's just annoying! the bible clearly states that the earth is round and is the first book known to say that, and there you go claiming atheist have a better understanding of the shape of the earth.
God is super-intelligent, yet that's not his best trait. So u say if God created by evolution that makes Him intelligent in your eyes? Since when did we say atheists are the gold-standard of intelligence? so God has to fit a description that best tickles your fancy? Crating life in an instant makes Him God-Almighty.
