I have a question

[Silver]

But say God wanted to make this life a test for human beings.

Then he would be a rather selfish, immature god unworthy of worship.

do you honestly expect Him to come down on earth and say 'Look people, Im here!'?

Sure, according to the bible, he has done it in the past. There is no reason he cannot do it now, unless he does not exist.

The evidence IS here, but you are refusing to consider it.

There is no evidence. All any theist has is faith, which is the veritable lack of evidence.

This means there is intelligence behind the universe.

False, you are merely attributing everything to god because you are intellectually lazy and you want a readily easy answer to questions that we honestly do not yet have all the answers.

I think many of you don't know who 'God' is.

One can know your god as well as anyone can know a fictional character.
