I never suggested that every scientist independently and recursively verify every piece of previous work. Work and verification of work builds on each other. And every once in a while, we have a major milestone that verifies that much of the work that went into accomplishing the milestone (such as the moon landing) is generally correct.
That's how we teach science to people. It's not just "here's the math and the science we know and it's totally right, just trust us bro". We say "here's the math and science we think is right, now let's do experiments along the way to periodically verify that the things we're teaching you actually generate real predictions that match reality".
Science is all about being suspicious and verifying. Many (if not all) of the greatest scientific discoveries came from people questioning the established "truth".

Right- that's called trust. I can't independently launch my own lunar program, so I trust those that did... did.
