"atheists ... are sticking their heads in the sand, like ostriches, because they are afraid of the responsibility that comes with acknowledging the universe was created by God and that life on earth began by God"
What responsibility is that supposed to be then? Being nice to your neighbour? I already do that. Having to visit Mecca at least once in my life, dressed in white curtains? I'll pass that one 
I'm happy to acknowledge things that are true. The problem here is that you don't really know if there is a God, neither do we. You... believe.
"both capitalism and communism try to preach religion as just sentimental inhibitions and as a crutch for the feeble minded"
I didn't realize capitalism was the enemy of religion. Capitalism happily uses religion as the barbiturate of the masses.
"but there are big questions. how did we come to be here? why are we here? and where are we going?"
We all ask those questions, but only you pretend to know the only answers.
"i strongly object to the hijacking of science by atheists"
What on earth do you mean by that? 
"how does each discovery lead to a conclusion of atheism?"
In two ways:
(1) By proving the religious myths as completely false (ex: Earth was created in seven days, this creation took place only some thousands of years ago, people were created precisely the way they look now, earth is in the centre of the solar system, etc)
(2) By increasing what we know about the universe and decreasing what we don't know (and hence might attribute to a divine power)
