Do atheists need some faith?

So you're equating reality to a known physical object? Why?

No equating, comparing. You understand the difference, don't you?

The point is if you don't know how big reality is, or what it is, you're choosing to determine what it is based on what you know.

There is a big difference between "how big" and "what". The question of "how big" isn't even applicable here.

You're looking for science to prove what is beyond science?

You have a reason to think it can't?

The question does not apply to what scientists look to establish, but the value you assign to what they have, or seek to, establish. Try not to portray your position as a scientific one.

Mistaken again. Scientists do not establish everything in terms of value.
