Is this all life has to offer? Food, sleep, fooling around, work, sex, death, and constant thinking about our existence? Is that it? No proof of God, no proof of a soul, no proof of life after death, no proof of spirituality being real, the only proof we have is that we live in a material world with a guaranteed trip to the grave in the end. IMO, the only difference separating us from the beasts of the animal kingdom is our "larger brains" and language.
