I think it initially requires faith to believe in God. But after the years oneís faith can mature to a place where itís just not faith but tested faith. A faith that is based on personal experiences of seeing prayers answered, observing miracles, communication with God, and God communicating back.Atheism absolutely requires as much faith as any other religion.
Science uses the senses to repeatedly observe tested hypotheses. The fact that we're not able to sense God with our standard senses exempts this whole topic from science. You can't prove one way or the other. Anyone who tries claiming God exists or doesn't exist is saying so out of blind faith, and nothing more.
Logically speaking, it's easier to assume there was a creator of the universe. However, it is also possible to logically conclude there was not. Logic, reason, nor science are able to give a definite answer on this, and any claim for a definite conclusion one way or the other is based on faith.
Once an individual has tuned in their spirit with God and has learned how to communicate and listen to God. They are now living in a place beyond faith but in absolutes.
