relegions are talking about after death lives

religions are talking much about after death, lives are eternal and who posted in heaven will have no works to do, I doubt this is far from fact because humans are not robots so willing or thoughtfulness is necessary for living, so works is necessary for us.people who posted in heaven mostly having sex but there will be no result because no child will come after doing this and this predicts that you become a machine, if the eternal life begins after death and has no end then they become like god, this prediction looks lucrative and a definite lie. Only the greedy souls are seeking happiness in religions no rational man can find hope in this way and I think they are put some pressure in our daily works by hanging this lucrative prediction.
