“What I could never understand is the following:
If all of life originated from one cell,”
You’re right, you don’t understand it. No one suggests one single cell, or even one type of one-celled organism. That’s why it’s a primordial soup, not the primordial amoeba.
"how could that animal become a plant or that plant become an animal?”
Those organisms hadn’t yet invented plant or animal. They differentiated later on.
"Evolution presupposes more impossibilities than creation, and unlike creationism there exists no supreme being capable of doing the impossible.”
This is why the effort to explain life’s diversity does NOT use impossibilities. It actually attempts to describe events that are possible, however remote the chances are.
If you calculate that something has one chance in a million of happening in a year, and we wait a million years, then the odds are about 1:1. If we wait a billion years, then it’s pretty much inevitable.
"In other words, evolution by any definition in the mind of any thinking person cannot possibly happen.”
That YOU say impossible is not terribly useful in disproving the evidence that it happened.
“ The entire theory is based on science which cannot conform to the laws of science.”
Feel free to point this out.
“ It is circular reasoning in reverse;”
The reverse of a circle is a circle. If it’s reverse circular logic, it’s just circular logic, idiot.
“How these people can claim to bear rational argument is beyond me.”
And finally, a statement i cannot find any fault with.
