To some degree, it is the willingness to "know your place" in human history. No one in ancient Greece could have discovered cosmic background radiation or observed that all galaxies exhibit redshift, which would have provided evidence for the existence of a Big Bang. Similarly, we have limitations to what we can observe and measure. We strive to continuously make improvements, but we also need to accept that not all questions will be answered within our lifetimes, and unless civilization collapses, schoolchildren will have a more complete understanding of the nature of the universe in 300 years than we do.
