Present a BETTER worldview

[TheDarkestOfAngels]

Yes it is no matter how much i despise it

Also mind that is for communicative civilizations, not planets with life or planets with civilizations that can't communicate

It does also ignore the difference in time in which these civilizations formed. Humankind came into its technological advancement in a geologic blink of an eye due to factors that we're still coming to understand. Even the civilizations that can communicate may or may not be able to communicate necessarily with us in any realistic fashion - which is to say that perhaps due to differing telecommunications technology or even just a wildly different method of direct communication.
There could be life on every other planet out there but those differences alone would make communication extremely difficult.

For example, a race of humanlike aliens (think star trek) may have come into existance on a planet similar to ours. In any important respect, they're very similar to us (perhaps they're Vulcans), and they live in a solar system within a mere 50 light years from our planet, but perhaps they did their search for life outside their 150,000 years ago, but nowadays they're barely the same species and become something completely different due to the progress of their civilization. Or perhaps they didn't accept Surak's teachings and they blew themselves to kingdom come.

It's really difficult in this respect to even guess as to what might be out there when we ourselves are still just starting to understand the universe when just a mere 100 years ago, most of the technology we take for granted (and are using for these searches) were still very new, let alone a thousand, a million, or even a billion years ago over the course of the 13.7 billion years of the universe's current existance.

An entire civilization could have lived and died in orbit around one of the three stars in the Alpha Centari system over the course of millions of years and could even still be alive in a form incomprehensible to us or they simply moved out of their solar system into a universe of their own design and we may absolutely never know about it. The implications are astounding.
