As far as knowledge and understanding go, most of us seem to arrive in this world with a clean slate. If, as the excitement and fun of playtime begins to wane, we decide to contemplate the longterm, what may lie ahead or perhaps where we came from, the information on offer becomes a bubbling mudpool of possibilities - obviously intended to confuse. We are told we are here for a short time, until death, but we are also told we are immortal. Orthodox science ( what our mainstream scientists are qualified to), is physical only, but the officially promoted reality which precedes formal education by thousands of years uses the spirit word - while spiritual evidence was suppressed (witch hunts). Regarding where we came from, take your pick. We could have evolved from monkeys but they've probably been evolving into different forms of monkey - sure haven't been replaced through incompatibility with the environment. We could have been created in 6 days of creation - so why create galaxies of unsuitable planets. The official line is we are the only intelligent life but could discover other forms if the distances weren't so large. Perhaps a cosmic accident - one success out of millions of mistakes? Regarding planet Earth. It was until fairly recently the centre of the Universe - now isn't the centre of the solar system and apparently our solar system is at the end of an arm of a spiral galaxy - as far from the centre of the galaxy as possible.
