"If (as is commonly accepted) the natural phenomenon of evolution had no end in mind when it created all living things, it is incredibly intelligent [...]"
Stop anthropomorphisizing evolution you stupid fuck. Evolution did not "create" anything in the way you mean it and it's certainly not "incredibly intelligent" as it's not an entity.
"but it forgot that they would go spinning into space without the law of gravity."
One: What the fuck? Two: Evolution did not "forget" anything because it doesn't know anything. Much like you.
"So it was fortunate for us that gravity just happened to be around to stop that disaster."
Yes. Gravity was just strolling by when its old friend evolution was getting ready to create life from all the chemicals just floating around a primordial pond. Gravity then said, "Good thing I happened by old pal. If I hadn't been here you'd be screwed as your creation would go flying off that little planet."
God damn you're a stupid fucker, aren't ya Ray?
"Where did gravity then come from? If evolution had nothing to do with it, who or what created it?"
It's an inherent property of the universe. You may as well ask where time comes from.
"Chance" or "accident" is too bigger leap of blind faith for me."
Now, now Ray. I find that very hard to believe after you filmed yourself explaining that the banana proves your god exists. After something like that there's no leap that you can claim is too big for you to make.
"The evolutionist's version of "just believe" isn't good enough. I want verifiable scientific facts."
You wouldn't understand them Ray. Trust me. Just stick your head back in your Bible and live out your days in blissful ignorance.
