Humans are born and they die. When we are born, is energy created? Or is it just some amount of energy that our mother gives us? Doesnt she take this energy from the surroundings? If so, then when we die, where does this energy go? It can not be destroyed.....

Just as an example to make this clear, if there is a fat man in question (like me :) ), when he dies, where does this "potential energy" stored in the fat, go?

Please give due thought to it before closing this, or calling it as silly.

Does this sort of prove that there HAS to be an afterlife, wherein we start with the energy we had when we died?

If you are cremated after death, all your fat will get burned and convert to heat energy.

If you were buried, your body would decompose, turn into some other form of chemical energy and then get used up by the organisms in the soil, somehow eventually turning up as heat.

So energy conservation is still valid, and no your energy does not need to go to some afterlife form!

Ok, consider another problem. If the population is rising, then how is this delicate balance of energy conservation holding? ie, If less people are dying, and more are being born, where is the energy coming from? Will it finish off? – Saurabh Raje Aug 14 '13 at 17:17
Energy of the people doesn't necessarily have to be constant you know. That law is valid for everything there exists, dead or alive. Very loosely stating, more population rise is leading to lesser forests... that can explain where the extra energy in human population is coming from. – udiboy1209 Aug 14 '13 at 17:20
I'd recommend that you remove that "You're a..." comments, and just focus on "If you..., then... If you... then..." – centralcharge Aug 27 '13 at 13:37
@DImension10AbhimanyuPS, I removed an irrelevant comment anyway, but were you talking about my answer? – udiboy1209 Aug 27 '13 at 13:56
@udiboy: Yes, the answer. – centralcharge Aug 27 '13 at 13:57
