You've never seen the core of the Earth, or mountains rise from sea beds, or a black hole. We use equipment and deductive reasoning to establish relationships between data and conclusions.Okay. But the people you hear actually saw it happen and could see it happen. Who saw an ape become a man or a fish become a bird?
I would say there is more evidence of evolution of lizards to birds than there is of black holes, not just from fossil studies, but from everything to genetics and microbiology to zoology, embryology, and virology.
