Yawn. Yet again Theland trots out his trite 'atheism and religious belief both rely on faith' claptrap.
No, Theland, like every other time you've attempted to pass off this lazy cut-n-paste pseudo-argument as somehow valid, it isn't.
Your argument is actually talking about the facts and arguments used to support of the concept of atheism, rather than atheism itself (one rather succinct way I've seen it put is this; "Atheism is a faith like not collecting stamps is a hobby." (unatrib))
Essentially, what you're trying to do is claim that science is the same as your religions beliefs. But science is not a belief system, so your argument fails even before the nurse can slap its bum and get it breathing. No belief is required for science to work.
Moreover, it's a most peculiar argument to make, even if you actually believe it. Essentially, you're turning an atheist's point of view back on your own beliefs;
"You keep saying we're basing our beliefs on irrational notions, unsupported by evidence... well, er... you do too! Aaaaaahhh!"
i.e. we're as stupid as you are... Yay, now everyone's dumb.
If your argument is from a position of 'You're guessing like we are', you've already lost.
