If you had any doubt in the existence of aliens then you can now be sure - they are definitely real and they even look just like us.
That’s the view of top evolutionary biologist Simon Conway Morris, anyway - and he reckons the likelihood of extraterrestrial life is “pretty high”.
In fact, he thinks it’s surprising that we haven’t already discovered human-like beings, given the amount of Earth-like planets that have already been detected.
He claims that because those planets are so similar to ours, life would develop there in similar ways to our own.
Morris said: “I would argue that in any habitable zone that doesn’t boil or freeze, intelligent life is going to emerge, because intelligence is convergent.
"One can say with reasonable confidence that the likelihood of something analogous to a human evolving is really pretty high.
"And given the number of potential planets that we now have good reason to think exist, even if the dice only come up the right way every one in 100 throws, that still leads to a very large number of intelligences scattered around, that are likely to be similar to us.”
Don’t get too excited by his claims, however - he also thinks that Earth-like planets will evolve Earth-like predators.
And that means alien SHARKS - and we don’t want them visiting us.
Morris put forward his theories in his new book, The Runes Of Evolution.
