I say we make it a simple data collection project. How many of the planets that humans have lived on developed civilization(questionable intelligence)?

Is this an average type star system?

So, 100% of the average type star systems we visited have civilizations.

Why fight over denials of the reality in front of us? Let's just assume for now that we have to prove we are intelligent enough to take care of our own place before trying to join the galactic family that is probably laughing at and wagering on our coming crises.
