Agreed, that is foolish to think that the planet will now or has ever maintained a status quo. It is, like life, dynamic.
From what I have read, natural selection is not an "idea," but an observed phenomenon in plant life as well as bacteria and in some insects. How do you think bacteria and viruses become immune to vaccines??? It's worth pointing out, too, that there is nothing in the process of natural selection that negates the moral teachings of Christ.
If you are implying that only environmentalists, atheists, and liberals "believe" in evolution, you are very much mistaken. Natural selection is like mathematics -- it's there whether you like it or not.
A hypothetical example: moths that, like people, vary in color, suddenly find themselves in an environment where the pale ones are easily spotted and eaten by predators, and the dark ones are not. The dark ones are the ones that remain to reproduce, and their offspring are more likely to be dark. Hence after a few generations, most of the moths are dark -- though never ALL of them, because genetics don't work that way -- there will always be a certain number of genetic inheritance combinations that some moths will come up pale, and vice versa. The environmental surroundings change so that suddenly it's the dark ones that are more easily spotted by predators and the pale ones that survive to reproduce, and within a few generations, most are pale. This is not an "idea" that someone has pushed, it's like math: it happens.
An entomologist who is a proponent of "outsmarting" bug pests as opposed to using pesticides, explained it to me once very well -- that plants and insects (short life spans, rapid propagation) are constantly one-upping each other throught natural selection -- the bugs go after the plants, the plants "evolve" (through natural selection) a defense mechanism, the insects natural-select their way to defeat the defense, and so forth.
I am a Christian and have a deep belief in God, Christ, and faith in the bible's moral teachings. I believe the bible speaks in parables much of the time, especially in describing geologic events. God works His wonders in strange and mysterious ways. People who deny natural selection and evolution because it's Just Not the Way God Would Do It stump me -- who are they to say how God works His wonders, and who are they to say that Genesis doesn't speak in parables?
End rant
Except when it comes to humans. And then, all people who are less than perfect must be euthanisized out of compassion.
