When the aliens do fly over they'll be wondering what the black and blue circles are in every other garden.
I must be an alien then
Enlighten me to these black & blue circles please

They're already here, everyone knows our technology boom was down to the crash in Roswell![]()
While I kinda agree with you there have actually been 5 mass extinction events, and a sixth is currently underway.

I suspect that in 100 million years time (assuming there are palaeontologists around to examine it) the fossil record corresponding to the 20/21 century will show the sudden deforestation of the entire planet and, in the blink of a geological eye, the extinction of almost all animals with a body weight greater than 25Kg, (with the exception of around half a dozen species whose population exploded!)
This represents a breadth, depth and rate of mass extinction that dwarves even the Permian-Triassic extinction (AKA the "the Great Dying")
If all this seems a bit pessimistic, it is worth noting that this has pretty well already happened over much of the developed world.
Unless something pretty dramatic happens over the next couple of decades the process will be largely complete, globally, within the lifetime of people alive today!
"Climate Change" is an utterly insignificant issue by comparison!
We are nowhere near finding other forms of life. The evidence we have suggests that life appeared on this planet only once in its 4.5 billion years of history. That suggests its an incredibly rare occurance.
Quick google seems to cover th basics.

Chance of finding non carbon life is pretty much zero.
Although the most likely form of intelligent alien beings mankind will encounter, if ever it will, will be robotic in nature. Robots could survive for so much longer than biological forms. If we can ever make sophisticated enough machine intelligences then they could survive the length of journey to other star systems carried by craft that we already have the technology to make, although the people who sent them would never know if they found anything.
But the fact that it appeared almost as soon as life could survive on the planet suggests that is not terribly unlikely where the conditions are right.
Okay, but having lots of locations doesn't mean there's lots of life.
Life could be plentiful, or we could be the only ones, we simply don't know.
Given the estimated number of stars to be 100,000,000,000,000,000,000,000 I think it is safe to say there is life on another planet.
No, it isn't.
We know almost nothing about almost all of the factors involved. It's not safe to say anything certain about the subject.
How many stars have potentially inhabitable planets? We have no idea.
What is the chance of life evolving on a potentially inhabitable planet? We have no idea.
How many of those planets (if any exist) have been stable enough for long enough for life to start? We have no idea.
And that's without considering evolution at all, just biogenesis. Nor does it take time into account - the existence of life elsewhere at some point in time isn't the same as the existence of life today. There has been plenty of time for life to exist, evolve and become extinct.
I find the whole,Planets and outer space thing weird..i mean whats the point in it all if it doesn't serve a purpose,I do also believe there isn't only us out there.
But makes me also wonder,theres also been sightings of unexplained objects in the sky and around out planet before,Why have they never made any attempt to communicate with us..questions questions.![]()
