I agree with you. It is all amazing. As for the water to the top of the Redwood, I will first say that I am not a scientist. My roomies in college were all into science, working on their masters degrees and some into such things as rapid cell division to try and get a redwood to grow faster. It was they who explained to me that it was a complete mystery how a redwood tree can get water to the top.
The explanation you say was offered does contain the word believe. I don't think it was purporting to know the exact answer, an admission that we simply don't know. We know some of what takes place, but we don't know how.
Happy to hear how I am wrong on this.
Perhaps you didn't know that when people refer to "capillary action," that said action is understood in terms of molecular attractions between water molecules which are themselves understood as electrochemical attractions between atoms which are themselves analyzed in terms of quantum mechanics, subatomic particles, etc. There is a leading edge of physics beyond which is a vast unknown, but the area you are insisting is a mystery ain't it. You are bludgeoning with your own willful ignorance. Again, the problem I have with creationism is not that you are doing it wrong but that you are doing it right.
Yes, I realize I'm not supposed to know you're a creationist. I haven't admitted being an evolutionist, either. I'll remove the mystery and announce it now. I have become an evolutionist. The creationists drove me to it last week.
