If you believe in creationism, then it is not compatible with evolution and the big bang theory or?

I would think it compatible. When I assume a creator, I know nothing about how exactly creation took place. The big bang can fit into creation as well as evolution. It doesn't necessarily contradict each other, is how I see it (except that I don't think of the big bang as an event that came out of nothing, so I agree with the conclusion in the text). However, I am not so keen on debating this aspect too much, because I find religion gets by with the given doctrines and offers orientation. Just to mention the ten commandments and the many practical and pragmatic elements of religion that come from them.

The feeling that arises from the questioning of conscience I can neither attribute to myself alone, nor to certain people, but rather to something undefined, which I consider to be God.
