First of all, science makes no claims to "truth", such matters are left to philosophers and theologians.
Instead, science deals only in observed facts and natural explanations -- theories.
However, much can be, and has been, observed about the origin of life and species on earth, and much that cannot be observed can still be explained by scientific theories -- regardless of your fervent wish to restrict science to current observable events.
Natural processes certainly include those which happened in the past, as well as those happening today.
Your claim that the past cannot be studied scientifically is rejected by science based on an assumption which is itself innumerable times confirmed: natural processes we see working today worked the same way in the past.
A good example of that is the relatively new science of plate-tectonics.
The world-wide movement of great geological plates can be, and has been, observed, measured and confirmed.
Continental plates move at roughly the same rate as the growth of our fingernails.
If we measure the rate of movement, and count up the tracks left by it, for example, we find the Atlantic Ocean is a hundred million years old, or so.
fortheDeclaration: "If science claims otherwise, it is 'science falsely so called' no matter what definitions it makes up."
Once again, the false-knowledge of ancient Gnostics has nothing to do with modern science, period.
The Bible is not at war against science, regardless of your fervent wish to make it so, FRiend.
Nothing can be observed about the origin of life, since no one was there to see it!
Your claim that natural processes we see working today worked the same way in the past' is a false assumption!
We know from the Bible that life was much longer before Noah's flood, so, you are assuming that everything is the same now as it was in the past, and have to use that assumption as your basis to make pronouncements on what you can't prove.
Now, once again, stop sending me your condescending posts.
Maybe you need to learn to read before you give lectures about science.
