It's not far away, we have examined millions of other planets and didn't find anything but some precious Gold and diamonds floating in space.
"Oh my, naughty naughty. Don't blame others for your failures."
xD Yea 'My failures' to believe all of this isn't a coincidence, your arrogance prohibits you to think rationally, that's 'Your failure'.
Sorry, but our technology to date, are only capable of very limited observations and we have never been to observe the surface of planets outside the Solar System, other than Mars. And that mission only allowed robotic vehicle, not humans on the surface.
None of our other unmanned space missions have travel to another star system - the nearest being Proxima Centauri, a red dwarf star, about 4.24 light-year away.
Voyager 1 and Voyager 2 are not pointed into any nearby stars, are the only spacecrafts to travel interstellar space, and both have being operational for 43 years. Voyager 1 have travelled only 152.2 AU, which is only 0.0024 light-year.
If Voyager 1 was heading towards Proxima Centauri (which is not), it would have taken over 73,000 years to reach this star, if we calculated this using its current speed.
The only to know if there are life in other planets, we really do need to be on the surface of the planets to explore, and that’s not currently possible with our technology.
At best, our technology is only able to observe the atmosphere of some exoplanets from other star systems, and that cannot us about life on the surface.
So we really don’t know.
You are simply making false claims from ignorance.
