It seems that people just love reading the threads but are either afraid, unwilling or unable to post a relevant comment?

Now then, many years ago I watched a sci-fi programme on TV about us Earthings being contacted by some beings from..... out there.

There was much conversation exchanged and the Extra Terrestials agreed to land here and meet us. I'm keeping this brief..... With much back and to conversation, the ETs were directed to a location where they were to land in the middle of an airfield. The craft eventually made it down to Earth but the Earthlings couldn't see them and were asking where the ETs were. Men were sent out to look for them. The view changed to inside the spaceship and looking out of it where it appeared to be amongst a tangled mass of "green stuff" (it was grass!). The ETs were complaining they'd been deceived.... Then..... an Earthworm crawled past.... just as one of the men sent to look for them accidentally trod on the craft and crushed it, never to be found.

The obvious conclusion of that was that the ETs were minute. Now then... I think that's the only way beings from wherever can travel vast distances at vast speeds without being crushed by the forces generated by such travel. ie, we're too big!!!!
