A top boffin has warned that aliens visiting earth will have all the same personality flaws that humans suffer.
Simon Conway Morris, professor of evolutionary paleobiology at Cambridge University, told the Royal Society that ET is less likely to want to phone home than call his broker to work out a way to shaft the earth for its resources.
He said extra-terrestrials are likely to possess human foibles such as greed, violence and a tendency to exploit others' resources, and are likely to show up to try and buy Manhattan with a chest of iPhones.
He said that Governments should prepare for the worst if aliens visit Earth because beings from outer space are likely to be just like humans.
While aliens could come in peace they are quite as likely to be searching for somewhere to live, and to help themselves to water, minerals and fuel, Conway Morris will tell a conference at the Royal Society, in London today.
He said that extra-terrestrials won't be splodges of goo … they could be disturbingly like us, and that might not be a good thing – we don't have a great record.
We guess he is talking about the record Let's Talk About Love by Céline Dion which breaks the Shadow Proclamation as a weapon war.
Conway Morris said that alien life is most likely to occur on a planet similar to our own, with organisms made from the same biochemicals. The process of evolution will even shape alien life in a similar way.
