Depends On If The Answers Are Satisfactory And If I Cant Find Others
Right, so really in essence. No. You will always be able to find other answers, or someone who has a different theory, I think the real lesson to take here, is to begin thinking for yourself. I am as guilty of this as you sometimes, in that I will read something and immediately adopt it without thought, before actually taking time to look into it.
Basically lostsheepwithoutashepard, the problem here is that you want me to argue you into Christianity. Which isn't going to happen. Not simply because I don't think I should do that, but it rarely works and provides a good and sound faith to base your life on. I could happily answer your questions, I would do the same thing you do which is to google up some info, read it to make sure I agree and then link you to it. You would read it, google up a counter and thus the wonderful google-circle would be complete.
By the way, it doesn't say that plants grow before there was a sun, it says that they were created before there was a sun, which is true.

Have a think on that one, if you wish to pursue this, I will happily oblige although it may serve you better to research these things yourself, as really that's all I will be doing, you should know that many issues with Biblical precision, come down to two main things:
A) Passages taken out of context and with the assumption that God is not omnipotent.
B) Mistranslation of the original scripture in Hebrew/Greek.
Cheers!
