Is the human brain really a tabula rasa or does it come preprogrammed to believe in a God?

The human brain is essentially a mush of electrical discharges, slowly ordered into a functioning system. Part of the way there one comes across nonsense syllables, where the brain is organised enough to make recognisable sounds but not yet organised enough for those sounds to mean anything to anyone else. Soon, meaningful words are discovered and placed in the mush, slowly collecting into sentences. Lists, at first, and then simple grammar is discovered and put to use. And so a language speaker is born. But the nonsense goes on, as the brain continues to try and make sense of the environment it is in. Superstitions are formed, like stepping on every floor tile, or following every crack in the footpath; and then, of course, it's on to belief in our Lord and Saviour Jesus Christ, who died for us and was resurrected so that we might not die but have eternal life. And then we discover science, and philosophy, and slowly, slightly more sensible concepts become embedded in all the crap. Jesus loves us, BUT, if we don't exersize, and eat right, we'll get fat and die.
