Calculation of the orbit against the background of stars is pretty standard fare for astronomers, even amateurs can do it................
Yet, by their calculations, they state that the moon is moving away from the earth. Using their own calculations the moon is currently moving 3.8 cm away from the Earth every year.
Calculating how old they claim the earth is, 4.5 Billion years, earths gravitation would have been too strong for the moon to get where it is today.
Stated differently, the moon should have been pulled into earth and crashed against at a minimum of 2.25 billion years ago, thus we would be a dead planet long before we could have reached the age of 4.5 billion years.
Taking those calculations into consideration, the earth would never have been able to evolve to where it is due to the extreme gravitational flux between earth and the moon.
Earth needed to have the moon exactly where it is, or close, long before just so the tides would be able to properly create the atmosphere earth needed to crate life.
One cannot take just a part of their calculations and ignore the rest. Either they are right on them or they are wrong.
Hey, I used their calculations, not mine.
Thus Everything was created by GOD, and thus the comment could not even exist until God created it.
