I think you are confusing the celebrity atheist Dawkins with actual scientists. I cannot think of one in-the-trenches scientist who has proclaimed what you suggest. I think you might be putting words in the strawman’s mouth.
Sorry, in no way did I mean to imply that Dawkins actually made any of the statements in my first post. These examples did however come from the mouth of actual scientists I have come in contact with. See my second post.
