Do you have links for the statement of scientists that have or do not have religious beliefs. Otherwise it is opinon
There's lots of material out there, mainly from the U.S. and the U.K., on surveys of scientists' religious beliefs. The Pew Forum on Religion and Public Life (pewforum.org) is the most active source I know of, here's a report on one of their surveys:
Pew Survey: A Huge God Gap Between Scientists and Other Americans - God & Country (usnews.com) That shows about a third of scientists to be theists, and there's another one somewhere that sampled the top level of scientists, members of the American Association for the Advancement of Science. I haven't seen that one online, I've seen it reported in books I've read. In that elite group the percentage of theists drops into single digits, if my memory is correct. I'll try to find that.
Based upon logical deduction, the amount of planets in the billions that could/can support life - We cannot be alone.
That's not a deduction, it's at best an induction, though the way you phrased it looks like just an assumption. We certainly could be alone, and we don't have the data to justify concluding that we aren't, the only thing we can say with certainty is that sentient life exists on at least one planet. We have no idea how common or rare it might be. Single celled life appeared on earth almost as soon as conditions made it possible, so that step might be relatively easy, but it took almost another 3 billion years for multicellular life to get going, so that step might be very difficult, and thus rare. Moreover, given that the cosmos is such as to permit sentient life to develop, somebody had to be first, maybe it's us.
But we're getting pretty far off the topic of the OP.
