Do atheists need some faith?

[genkaus]

This perspective mirrors a theist's perspective on why a god must exist.

And since the perspective is regarding an unseen, unknown entity rather than a time-tested methodology, it is irrational.

You've bypassed the point by stating our reality is reality (in an absolute sense) and then compared to our collective imaginations.

And you have ignored it by questioning the tautology of reality being reality.

So earth's smartest species is capable of assessing absolute trurh?

If there is such a thing as "absolute truth" then yes.
