Life can not exist on other planets We have new technology popping up every day and if we have not found life by now then there is none. Also in the bible it states god created the heavens and the earth sure there are other planets, but it never said anywhere in the bible he put life on other planets. Some people may say non believers are being unreasonable but there is no proof still to this day.
I think their is a lot of proof that life on earth is not the only life in universe and it would be egoistic and selfish that we think we are alone in universe im not religious fundamentlist to belive in every word of holy bible that can only limited your free thinking and what about ufos that lot of people had see including my self ,..i belive that somewhere their is technology for traveling to space maybe we have that technology but they hide it from us or we have a lot of visitors from out of space and they are probably among us
