Cassiterides, I recommend that you think more about the words you use. An intellectually honest way to make the argument you're currently making would be to say:
"I can't personally see how the theory of evolution can explain why humans are so helpless during the first years of life, compared to most other animals, and therefore I find the theory unsatisfactory, at least in this case. Can anyone offer some thoughts about why it is so, from an evolutionary standpoint?"
You see the different between this and what you're currently doing is? Humility. Openmindedness. Intellectual honesty. Logical thinking.
When you essentially say that "I don't see how evolution can explain this, therefore it's false" you are not only making a logical fallacy. You're setting yourself up as an omniscient authority. You're saying that "I'm right and nothing you say can convince me otherwise".
Is such arrogant behaviour really what you want people to associate with christianity? Isn't it likely that such behaviour would rather drive people away from your religion?
