Whatever you, I or anyone other sceptic for that matter thinks about Christianity, there are lots of smart people who do believe. And whilst belief in a supernatural power is lower in the science community, according to
Pew Research (2009):
...just over half of scientists (51%) believe in some form of deity or higher power; specifically, 33% of scientists say they believe in God, while 18% believe in a universal spirit or higher power.
The research also states that in the science community 10% identify as Catholic and 21% as protestant.
