Do atheists need some faith?

[Mystic]

If so, isn't there a little faith involved that there really isn't any evidence for theism that may have been overlooked or yet to be discovered?

If Theism rests on an argument that is yet to be discovered, then I would say, God doesn't really care to be known by humans if he exists.

Theists insist God wants to be known, so it's problematic. Also, if Theism rests on a proof to be discovered, then belief in it will be cold type reliance like belief in a mathematical proof after seeing the proof.

Also, science maybe able to prove a Designer, rationally it's possible that it does, but it will never be able to prove that Designer is good, unique, great, loving, etc...
