The Virus, the Evolution, and the Creation

It seems for the most part, when someone says, "I have a virus", they are talking about a bad invader. Fact is, not all viruses are wicked things, since some are actually beneficial. You could even say, "I have a virus" without meaning something that made you sick, because we have virus variations inside us already.

Not all viruses are bad, and some are essential. Exogenous retroviruses are the stuff of evolutionary legends, and now we have speculation that because they affect the brains of mice, they must have played a part in human evolution. Not hardly.

Imagine taking the train out of Galveston. Some of the passengers seem to have always been there, and even have their own duties. Then some bandits come along and not only rob the passengers of their money and jewelry (and my best pocket watch!), but they start changing things for their own destructive purposes. The passengers who look like they've always been there can be likened to endogenous retroviruses that have functions, and the bandits are like exogenous retroviruses that come along and wreak havoc.

Endogenous retroviruses are essential for the development of the human placenta. Working from their worldview, evolutionists have no idea how they got inside us, so they assume that they are remnants of invading viruses in our past. Of course, this is faith-based speculation, since they have no evidence or eyewitness accounts of what happened those alleged millions of years ago. It makes more sense that they were put there by our Creator.

Research on mice reveals that endogenous retroviruses are important in their brain development. Good observational science is once again being fouled up with evolutionary speculations about how the stuff was probably a part of our evolution. Declaring "evolution" by offering guesses without evidence pays well; I'm in the wrong line of work!
About 8–10% of human DNA, as well as the DNA of animals like mice, consists of scattered DNA sequences matching those of retroviruses. These sequences are called endogenous retroviruses (ERVs) because they are actually a part of the healthy host cell’s DNA. (Exogenous retroviruses—like HIV that causes AIDS—come from outside a cell and infect it.) How ERVs came to be part of our DNA and what they are doing there have been the subjects of much speculation and research. Scientists have known for some time that placental formation depends on ERVs. Evolutionists credit such viruses with making mammalian evolution possible. Now scientists have shown that ERVs play a crucial role in the development of the mouse brain.
