Question:  Is Stonehenge a result of alien life?

Answer:
No one really seems to know.  Scientists have been investigating
it for a very long time, yet no valid conclusions seem to have been
reached.  Some people think aliens did it (probably not), some think
ancient people did it with a little ingenuity (probably).  The
Pyramids in Egypt are the same way.  It took tens of thousands of
people about 30 years to build one pyramid, so given enough time
it seems anything can be accomplished (no matter how impossible
it may seem).
