I believe in the bible. I believe in surrendering to God and let him direct us. Mark 12;29-31 but?

I am quite sure there are other life forms out in this hugh amount of space. We are Gods Children. There are other galaxcies, universes, and other dimensions, perhaps, but I wonder will mankind have to wait until we can utilize more of his brain power , or will we get to know more about the afterlife in this 21st century?
