Atheism, just like Christianity, is a faith.

No, it's not. The hypotheses there exist no god, is quite scientific. It's scientific because it can be falsified: there exists a way of showing the hypotheses is false, namely showing there is a god (just point out one).

The reverse, there is a god, is not scientific, as it cannot be falsified (you can't prove no gods exist). It is therefore a faith.
