That's what science is supposed to be. I wish it actually where the case a lot more in the real world. My study area is astronomy, not biology, so during my fores into this forum, I am a bit out of my element. Astronomy and cosmology is a marvelous field of study. Advances since I got into the field have been breathtaking.
New theories arise and old ones fall rapidly.
It's a marvelous time to be involved in astronomy and cosmology. The only difference is the degree of bluster by the adherants. The formation of life from nonlife. Life is fantastically more complex than anyone ever realized. It certainly did not form randomly.
