The thing is though that you can explain some things through christianity and have absolute proof. But you can explain more things through science. I recently saw a clip from "Young Sheldon" he was talking about how the odds of our universes gravity being as it is, just a little stronger and everything would fall to the bottom, a little weaker and nothing would be able to combine so nothing would be larger than an atom. you cant tell me that we just so happened to: have a universe that was created from nothing by chemicals that still so happen to exist and have every kind of herb, metal and animal we would need to treat most diseases and evolve yet not enough to get further than the moon. if the spirit exists, than the spirit world (aka Heaven) exists, and if an alternate universe can exist in another reality, than Heaven can exist too, if Demons exist, which we see everyday but we dont pay enough attention to notice, than Angel's exist too. Many men are lost in the way of christianity, it's easy too do so, but my family knows what is the perfect balance between the Dream-like-yet-real existence of god, and the earth we live on. Life is a trial, so when you die you will be judged for your actions. So Please take heed.
