As a scientist, I would think you'd be more of an agnostic than an atheist. Being an atheist sets a definitive no. However, an agnostic gives you the scientific position that what we currently think is supernatural could be explained. It may not be a god in the historic stature. It could be a fuller understanding of the universe and those in it.
Maybe those "powers" are explicable, but we can't do that yet. A hundred-fifty years ago, planes didn't exist. We can send vehicles to Pluto and beyond. Think of what may happen in the next 150-200 years.
Most Jews and Roman Catholics believe The Bible is allegorical. No one was turned into a pillar of salt. There was no ark (think of the smell). Could there have been a 900 year old man (other than Mel Brooks)? Maybe it was a "person" from another planet. Hell, even in Bill Maher's movie Religiosity, the Vatican's astronomer said are were beings elsewhere in ours or other universes. Unlike other faiths, the priest said, life on other planets would not disprove our current definition of faith or God.
