Throughout the years we have learned a lot about how our bodies function and why they do the things they do, scientists have been VERY wrong in the past and some medical procedures have been very unsuccessful, and looking back we are all collectively like wow we were so dumb. But how do we know for sure we are correct now? Like how did we learn that the ovaries producs eggs that become fertilized by sperms and how on earth was this discovered and tested? How do we know its our thyroid that regulates hormones that effect other parts of the body?

The truth is we don’t “know” a lot of things with 100% certainty.
We are usually just very confident because we have disproven all of the competing theories. Eventually you are left with theories that have survived being disproven for decades, centuries or even millennia.
