Congressman shows never-before-seen video at military UFO hearing

14. Here's an illustration of the math involved here

If we put people in the fastest spacecraft ever created by humans—NASA's Parker Solar Probe, which reached about 430,000 miles per hour—and aimed it at the nearest star system (Proxima Centauri, about 4.25 light-years away), it would take roughly 6,630 years to travel that distance at its top speed. However this probe does not have the space, nor life-support systems, for humans.

If we sent a human crew in a spacecraft as fast as Apollo 10 (about 24,791 mph, which remains the current record speed for a craft with humans onboard), it would take roughly 115,000 years to reach the nearest star system, Proxima Centauri

That's the CLOSEST other star from our own.

Now, how common is advanced life thought to develop on other planets?

For advanced/technological life, “one in billions” of habitable planets is often used as a scientific boundary for pessimism.

Optimistic models allow that advanced life might occur on “one in millions” or even “one in thousands” of habitable planets, but this is not yet supported by evidence

IOW, it's extremely optimistic to think even 1 out of 'thousands' of planets EVER develop advanced/technological life, and it's more likely to be 1 in millions, or 1 in billions. And then there's the fact that this advanced life needs to exist at JUST the right time, such that they happen to be able to reach earth (from 1000's to billions of light years distance) while humans are around to detect their arrival.

These numbers mean that I don't think I need to consider the possibility that it even COULD happen that we're visited by alien spacecraft EVER, let alone craft that are buzzing around in earth's skies right now.

I frankly think it's about as likely as the chance that if I drop this brick it will just float in the air, rather that falling onto my carpet, because all the known universal laws of physics/time/space were suddenly suspended.
