You can make naked eye observations but it took the telescope (and more accurate time keeping) to have accurate enough measurements for an actual proof. Multiple ancient Greeks who had strong arguments for Heliocentrism, but there wasn't enough empirical evidence. That took Keplers Laws and a telescope. It could not have been proven without the necessary level of technology. The same is true today. Except we know our theories are incomplete and in many cases we know under precisely which conditions it's incomplete. We simply can't access those energy levels to reach the next step yet. We also know constraints on what can be possible while keeping most of what we think is true, we lack the ability to go further than that however. So we are waiting for the technological breakthroughs to prove or disprove our many candidate theories. It's like Kepler waiting for Tyco's telescope data. We can't rule things out without stronger accelerators or radical ideas that are actually testable.
