heres the official truth on all matters (im always a 100% right so listen up!)-

god doesnt exist in any form, if aliens do exist they have never reached earth it would take too long and the speed of light cant be broken (faster you get to light speed you slow down because you get significantly heavier).

man exists cause we evolved from long a exstinct primate, which itself evolved from a lower life form, this proberly happened a couple times (evolving from lower and lower animals), originally evolving from simple cells and bactaria. bactaria came from natural elements like hydrogen and other shit that under the right conditions formed life, these elements came from space they always existed (time is more or less a human concept), the elements expanded to form stars planets and all life after the big bang, big bang was all matter put in a small space until it finally expanded, before that atoms n' matter just existed forever (time doesnt exist without a sun) and thats how your here today.

you die and you simply wont BE, no afterlife or reincarnation, it'll be like before you where born, remember that? well thats all our futures.
