as for other life forms, who knows, maybe there are so many other planets with far more advanced beings than us.

who would want to visit 'earth' ?

most of the inhabitants know nothing,

we fight each other and look like destroying the Planet we live on. Most of this effort is to make sure the rich people gain a few more dollars more.

In fact we are pretty basic when it takes all our effort just to get a few miles into space.

would anyone drive their cossie around the globe 100 times to look at some ants building a nest in New Zealand.
