Now I don't have a problem with Homosexuals or what they do... they can do what they want. But wasn't man meant for woman? Sperm cells instinctively have tails to swim in search of egg cells to penetrate them, what are they swimming for if they end up in another man's anus?

How do scientists know a skull belongs to a certain ape if like humans, monkeys can have different head shapes
The skeletons we see in text books and in the museums all seem to have the same head shape...but blacks, whites, and asians all have different head shapes...(longer, rounder, etc...)how do scientists know if the skull they are looking at then is human...and how do they know that a skill belonged to a Neanderthal since they probably could of had different head shapes as well?

and from what race does that model skeleton we see come from (taking into account it's skull shape)?

How did sex ever come into play with evolution? Why would it have been beneficial instead of cell division? Do you think that evolution could bring two different cells through different mutations together that would be able to mate together creating a female and male gender? What are the chances of that? I don't understand why mating would be beneficial when cells can just divide and multiply.

This thought once came into my head while thinkning of all kinds of living things and how they feed..which is usually off other things. I even heard fleas can have fleas, and the fleas of fleas get fleas...plants can get parasites, people get parasites, we over abuse our host (pollution ect, we can kill the earth in a sense). Has anyone ever heard this our Earth is but one planet a host) and we are all just parasites living off this same host. I dont believe this but Im surprised I never heard such a staement from an atheist describing how we are not neccesarily "higher" than animals because we are more adept.

Doesen't energy plus dirt equal us?Like when our energy leaves we turn into dust(or dirt). So we aren't just our physical brain we are also that energy because with out energy our vessel dies.

Just really think on this and then answer.

So in evolution where did the energy come from when the planet was all dirt before life started.

We had to come from dirt or some part of the planet.

When we eat the food transformes to our body.

Plants eat dirt , we eat plants so why coulden't a God make us from dirt with the breath of life(energy)?
