Edit: I'm referring to the Hubble "photograph"
It's called the Hubble Deep Field
Yeah with all that in such an extremely microscopic slice of what we call space... how can anyone truly doubt we are alone. The number of orbiting planets found in a single galaxy alone is a relatively large number. Granted, so many conditions have to be set for even the most simple of lifeforms to come to being, stuff like RNA and DNA alone take quite a "perfect" set of variables... but that many planets, and then that many galaxies... in that utterly pathetic sample of what we call the universe... we are not alone. Maybe somewhere something close to dogs, dolphins, or even apes might exist, in evolutionary terms of intelligence.
Then again, shockingly enough, life may exist, but radio frequency or some other radiation signature proving an intelligent lifeform is out there, might not reach Earth for another 10-14 billion years, considering quite a few of those galaxies in that image alone, are close to that old in terms of the light we are seeing. i.e. all the light/radiation coming from those furthest galaxies might be 10 billion years old from the time it originated out there, only maybe a few billion years after the universe formed. Considering Earth, and our star, are only about, averaged, 4 to 5 billion years old, and life wasn't even possible on Earth until a few billion years after the planet started coming together... and then the billion years it took life to go from nothing but cellular soup, to microscopic organisms, and then to animals like us... well, I think my point should be clear.
Basically, what we are seeing right now might be before any life, just like our Galaxy, was even possible. 10 billion years later, Earth might finally receive a radio transmission seeking other intelligent life, similar to what we have been doing.
Can we wait 10 billion years? The human species, iirc, hasn't even been around a million years (ancestors and whatnot, and the missing link, not counting, just homo sapiens).
What would it even be like to say your species has been around for billions of years. Hell, even millions. As an advanced, intelligent organism, Earth hasn't even held something like that for even hundreds of millions of years. Mammals haven't been around that long.
Woah. I just blew my own mind. I gotta go before I do any more damage. I have a midterm tomorrow.
