Impressive. In fact, so impressive i'd suggest you submit it to New Scientist, or any modern day science journal. */sarcasm*
However, not understanding how you turned from a bit of willy milk into a full grown human does not give rise to believing in an invisible entity or any form of planned creation. Ok, you don't know the answers, everyone's in the same boat, (including those people who wrote books thousands of years ago that you trust with your very life).
Happily confess your ignorance to the world- it's nothing to be ashamed of. Mankind has a long way to go on the road of discovery so admitting lack of knowledge at this stage bears no problems. What is pointless and frankly rather stupid is to say "Well, sperm looks clever so there must be a god." The only other evidence you have suggesting such a thing was written by people who didn't even know what caused an earthquake, thought there was a big dome in the sky holding water, and considered the world to be flat as a pancake. They were wrong, that's a fact- what in the world makes you think they'd be right on anything- especially when concerning the existence of a completely undetectable being? Unless of course he got up and said "hi, i'm god" - in which case he IS detectable and as such there's nothing to suggest we too wouldn't have seen him sitting on the top of a mountain barking orders, telling us to kill our children if they're naughty, and to remember to cover our poo when he's in the vicinity, cause he finds it detestable.
But looking at all historical records, all texts of this nature, what is it that these people really witnessed? Ah yes, the ACTS of their supposed god --------- Earthquakes, floods, raining bloody sulphur whatever. Things that can easily be explained by science in our modern times. They didn't know why or how- we do. People in those days couldn't even figure out why the wind blew, and promptly blamed it on wind carrying angels. Everything and anything had a governing "concious" entity. (Whether the same entity governing all things, or a multitude, it all comes down the same).
Those people knew fuck all about the world and the way it works. You are following in their footsteps and buying into the greatest feat of ignorance simply because sperm confuses you.
Furthermore..... Even if you wanted to delude yourself and state there was a big invisible entity that created humans, pubic lice, and aurora borealis, what in the world would then give rise to assume this entity wants you to bown down and practically suck his dick, and if you do so he'll give you a second life after this one has finished? Of course whatever you say, this is just a test and in your next life you wont have to put up with all the horrible scary diseases and mean people like murderers, alcoholics, and faggots. Depending on whose particular version of god we're talking about, he might order you to chop a bit of your dick off, sacrifice goats, blow up america, or stone women to death if they dare show their face in public. All these orders coming from an entity people keep telling me is completely undetectable. If he is detectable, we'll find him/her/it and you'll hear about it on cnn. Of course if you had something slightly better than "look at sperm, it's so fucking amazing", as evidence to suggest plausability- you'd probably be taken slightly more serious.
The next thing I remember was me repeatedly poking my dad in the forehead and saying....How does that feel dad to be poked in the forehead?
After which your dad went to smack your ass, then realised you have a tail bone. "Why the fuck would my child, who has no tail, have a tailbone? Hmmm this god entity sure is a stupid fucker."
