Liverpool - Cretinaceous Era ne'er-do-well nomads first settled in Sefton's Lunt Meadows circa 5,800 BC according to a new report tracing human/alien hybrid habitits - er...habitats! - north of the Watford Gap.
Consultant archaeologist Prof Doug Trenchiss said his team found evidence of radio carbon dating among Stoneagers who regularly took part in Long Wave radio station phone-in chats with rough 'n' ready female ETs.
A lot of cross-fertilization later the area teeming with thousands of cross-bred offspring who, within 69 years, colonised much of what is now North Toxteth.
"It's from these human/alien strains that the modern Scouser is descended, like," Prof Trenchiss commented.
"We've also found this genome pops up in the most unexpected places such as among Southern Baptist Snake Charmers and branches of George Bush's family."
Cherie Blair is daft as a brush.
