Redshift, Metals, and Population 3 Stars

Hands at the Darwin Ranch over by Deception Pass ride the Owlhoot Trail, hijacking science and getting our tax dollars to spin yarns to gullible Darwinoids. They like to tell tall tales by the campfire, and several of those involve the Big Bang. Instead of God creating the heavens and the Earth, it was done by the Big Bang, cosmic inflation, and whatnot. Since evidence is against this concept, the stories, they just keep on a-comin', even though some folks say that the Big Bang didn't happen at all.

After the Big Bang, laws of physics hadn't sorted themselves out yet, since they were violated by the original singularity. All that hot gas eventually evolved stars and galaxies (for the gas clouds to form stars goes against the laws of physics, but that doesn't matter at storytime), and eventually you and me. Secular cosmologists believe that different stars formed at different times (although blue stars foul up the works and affirm recent creation, but again, that doesn't matter because it's storytime). In this story, there are three kinds of stars, and secularists think they've found Population III.

Secular astronomers think they've found Population III stars, which would support the Big Bang conjectures. What has really been found, and is there any evidence that doesn't commit logical fallacies?

A galaxy way, way out yonder named CR7 (for some reason, named after Portuguese footballer Cristiano Ronaldo) has signs of Population III stars in this story. By what basis? There's the redshift for time and distance (funny how we don't hear about the blueshift, such as the Andromeda galaxy exhibits), it contains "metals" (not gold or platinum, astronomers have their own definition for "metal", which is anything heavier than hydrogen or helium). Also, there's bright stuff. Seen any individual stars that qualify? Not hardly! Are there other factors to consider in the redshift that are being conveniently ignored? You betcha! Do they use affirming the consequent and other logical fallacies? Naturally!
Astronomers classify stars into three types: Population I, II and III. Population II are those generation of stars, which allegedly formed from the Population III stars and have only a low metal content. Population I stars were allegedly the last to form, hence are the youngest and hottest stars and those with high metal content. Population I and II stars were historically first identified in our galaxy. Population I stars are found predominantly in the spiral disk of the galaxy and Population II stars are found above and below the disk. They have other distinguishing features also but their metal content is the major distinguishing feature.

Those early-generation stars also first formed into small galaxies that later by merging with other galaxies grew larger, or so the story goes. Growth in galaxy size and in ‘metal’ content is called ‘galaxy evolution’.

“The first generation of small galaxies was likely well in place 400 million years after the Big Bang. Following this initial phase of galaxy formation, galaxies then went through an extended phase of merging and coalescence with other galaxies, whereby they built up from masses of several thousand solar masses to billions of solar masses. This buildup process extended until the universe was roughly two billion years old. Then, due to some feedback process—now predominantly speculated to be AGN feedback—it is thought that this buildup process halted and gas accretion and star formation in the most massive galaxies halted and galaxies underwent a much different form of evolution. This later evolution continues to the present day.”
This is the big bang evolution story, but it vitally needs those Population III stars or there is no story. Now it is claimed that Population III have been found in a very distant galaxy.
