If some of our tourists were aliens it would explain why so many will queue up for hours to look at virtually anything for £25. Madame Tussaud's is thought to now rely on aliens for 90% of its business as most humans have seen other real humans in real life.
Cultural misunderstandings may also have taken place with visitors from outer space having little idea of our funny earth ways. Their intrusive probes have caused consternation among natives, though some seem to like them. We say 'abduction', you say 'intestinal probe party'.
The presence of aliens among us could explain how those towels get on sun-loungers so early in the morning. Many have blamed German tourists with little actual evidence. Perhaps it's time to blame aliens, with little actual evidence.
Of course earthlings are themselves moving ever closer to space tourism themselves. The first Virgin Galactic flights are set to take place in 2016, though they are likely to be late, over-crowded and take poor customer service to new frontiers.
For £100,000 you will be able to fly to the edge of space, float around a bit, then glide home. But it's a first step towards the day when we can land on other planets, buy tacky souvenirs and queue for hours to see aliens made of wax.
