Ok, so I'll stop you right there. Atheism is clearly defined and has nothing to do with any of your points! And I say that as a christian myself (though agnostic and also anti-creationist evolutionary biologist, but alas).
1. Well, yeah, it is even if you believe in Creationism. Or did god not create life out of formerly abiotic matter? I faintly remember something like that being written in the bible. Seriously though, it very likely is true. Not every atheist has to believe in it though. Atheism is just (and I quote) "disbelief or lack of belief in the existence of God or gods.". Nothing more, nothing less.
2. I guess you mean chemical evolution before the advent of actual lifeforms? Because that's pretty much the same as Abiogenesis. And still has nothing to do with Atheism. (Also, you don't seem to have anything against evolution itself I wager? That's interesting to note.)
3. Always with the absolute hyperbole to garner emotional reactions. No, abortions usually don't kill babies (except rarely in emergency situations to safe the life of the mother). And it's still not a prerequisite to be an atheist. It is blood libel against them though, so fuck you.
4. Most atheists I know would just object to the notion of objective morality and even then it is a hotly debated field both in theology as well as in philosophy. I know of people who are sure that there is some sort of Kantian objective morality which doesn't require a deity and others who have argued that subjective morality doesn't mean that there aren't morals which are pretty much universal (having evolved alongside us). And I hate the idea that you can only be moral if there is a god constantly threatening you with eternal hellfire for going out of line.
5. Ah, homosexuality equals pedophilia, the old classic slander against us gay people, conveniently ignoring lesbians of course. Again, fuck you! And from what I can tell there are quite a few atheist right-wing idiots who dislike us homosexuals just as much as you do, so what has this to do with atheism?
Well, according to our religion there was nothing and nothing happened to nothing and then suddenly God (where did he come from, what did he do before, what caused him to be? Never explained) created everything and then magically rearranged everything into self-replicating bits which he magically breathed life into. So where is the difference here aside from your smugness about it?
Oh fuck off with your "Poor me, I'm so unimportant without the whole universe revolving around me!" rethoric. Instead look upon the wonders of the material world, be astonished by its beauty and try to experience it in the one life you've been given instead of going on constant rants against people you don't like. Fidn your own meaning here (and if it's serving god, then so be it, nothing bad about it, just stop judging others for not following you.)
