I understand your point. But it is just silly to live one's life that way. I guarantee that you don't .... not in the real world, no one could.
Yes, in the science textbook ....(1) hard data is collected (2) hypothesis is formulated FROM the data (3) tests are made. But we don't live in a science book.
Even Einstein did mostly thought experiments using hypothetical data that RESULTED in testable proof. The Christian does the same thing. He decides to believe on Jesus Christ, and God in turn guarantees to bear witnesss in his spirit (give proof) of sonship, his existence, love, reproof, rewards etc. This is what happened to me. It is what has happened to EVERY single Chistian for 2000 years.
Now according to you, just because Einstein skipped step one, or just sorta worked it out in his head, then his testable and provable models don't deserve to exist. That's just plain silly.
Did you never color outside the lines when you were a kid?
