If all the observations support my hypothesis, it seems to validate it.
“If all the observations support my hypothesis, it seems to validate it.”
Not really, since as I said, if your thesis is true, your observations are limited to a statistically insignificant sample.
Besides, I think you’re overstating the amount of support actual observations give to your hypothesis. Some of the main propositions of evolution are still completely unobserved. Filling in those gaps with conjecture is not the same as actual observation.
