As far, as science has reached, and the religion, for the main time, I can say we are alone in this huge universe. But I see it's quite illogical that we are alone in a such huge universe that can hold Billions of Trillions of humans, even more. The question is are we the last or the first on the universe??
The universe age is 13 Billion and 800 Million years. Its very old, but we can be just the start of something spectacular, amazing, priceless, inamaginable.
