Researchers have calculated that up to 37,964 worlds in our galaxy are hospitable enough to be home to creatures at least as intelligent as ourselves.

Astrophysicist Duncan Forgan created a computer programme that collated all the data on the 330 or so planets known to man and worked out what proportion would have conditions suitable for life.

The estimate, which took into account factors such as temperature and availability of water and minerals, was then extrapolated across the Milky Way.

Mr Forgan believes that the life forms would not be amoeba wriggling on the end of a microscope but species at least as advanced as humans.

Mr Forgan, who believes it will take 300 to 400 years for us to make contact with our neighbours, said: "I believe the estimate of 361 intelligent civilisations to be the most accurate.

"These would certainly be the most Earth-like civilisations but the bigger figures are certainly possible. We can't rule them out.

"Most of the other planets we have looked at are older than our own – so I would expect to see more advanced civilisations than ours existing."

Ya know...the issue I have always had with estimates like this is that they are " measuring " the possibility based only upon our knowledge of what " life " is.

If evolution really is scientific fact, and every organism will adapt to it's environment, then it's entirely possible that what are known and considered the only building blocks for life, aren't necessarily so.

There might always be a need for one ( such as water ) but no, or at least very much more limited, need for others.

he hopes, he wishes, and how may variables did he include?frustrated

sounds like it's part of the evolution religion to me.tears

in an infinite universe, if there is one of something then there has to be millions of somethings

Yup and even in a finite universe that is as massive as just the visible portion is would mean that statistically, which is how this estimate was reached, we would have many many many planets with some kind of life on them.

I have no doubt life exists elsewhere. Intelligent life . .. who knows. We are the only species on this planet that falls under that category, and we almost died out ourselves some 150K years ago so who knows how rare that is to get started no less evolve as far as we have come.

I took a trip
On a gemini spacecraft
And I thought about you
I passed through the shadow of jupiter
And I thought about you
I shot my spacegun
And boy, I really felt blue

Two or three flying saucers
Parked under the stars
The winding stream
Moon shining down
On some little town
And with each beam
The same old dream
