if the present mimics that pattern in what now is a day cycle, it means only that the conditions are such that this is now how it works. A change so big, so fundamental, as to affect gravity, light, and the atomic and molecular structures of matter, and etc. reducing the growth rates, and lifespans and other things happened. It will happen again, this is what I believe. Now, you can say, believe whatever you want, where is the proof, and I say the same to you.
I see. Given the way you state this which is of the form of "last Thursdayism" or of solipism because it is not falsifiable there is no way to disprove your belief.
Science does make some assumptions which you don't accept and which are not falsifiable in your terms because you can always invoke God changing the universe to make it look the way you choose.
I think you know full well the basis for science. If you wish to characterize those basic assumptions as religion I won't argue with you. As to why they are taught in school. Well, that is the science that is being done now. This is how it's being done.
You can't prove to a solipsist that anything else exists. You can't prove to a last thursdayist that the world didn't come into existence last thursday. And you can't prove to a YEC Bibical literalist that that their explanations are false.
You of course are welcome to your beliefs. Fare well and have a good life.
