I wouldn't call myself religious and very devoted person too, I just know the stand point of the two major religious holy book, Qur'an and Bible says about how the world will end. The scriptures of both books are very similar. They start with talking about signs, signs that are ever getting stronger these days, signs like men becoming lovers of theirselves, boasters, blasphemers, disobedience to parents, unholy, distasteless biggots, worshipers of money, lovers of Satan and unholy desires than of God, and quiet a few more. We see all these signs today. They also point to other things like needless killings, increasing wars, sufferings and hunger, the coming of the Antichrist and finally, the second coming of Christ the bible says.
These are a few I can remember, correct me if am wrong.
Like I said, am not a devoted religious person. I like to keep an open mind all the time, so I can also relate to your point on how science explains the beginning of life starting from the big bang explosion some billions of years ago which formed our know world. It goes a step forward by describing how rogue meteorites and comets kept crashing into earth depositing water and other substances which eventually started the biological evolution of life. I think it's okay to say science has made believers out of us given the many unanswered questions in our religions, not that science doesn't have some too.
