That could still work out 'not necessarily to our advantage,' if we're the toilet.
Been thinking on this for a while and as a avid reader of Sci-fiction in my younger years I am trying to figure out what all this means to the scientists today.
We send space probes to planets we can not in fact go to, as humans yet, so who is to say some very different species from humans is not doing the same.???
Little green things that have an uncanny resembles to the human form, a head, eyes on both side of the nose, arms and legs--- is this not the height of human EGO that we believe only intelligent life form must all be built exactly like us---we do put wings on paintings of angles and represent God to look like a grandfather type person.
I am not sure man physically will ever go into space much further then we have done so now. It will be hundreds of years for us to get out there into deep space, so we sent robots to go before us and see what we as humans at this time cannot experience.
Mr. Tanker, we cannot physically go to the depths of the Mariana Trench but we can develop tools to see what is down there on our own planet. There are to some estimates of over a million life forms on earth that we are just now discovering hidden so far in places we only know about by discovery.
Our planet is slow to give up its secrets, some may never be found.
For scientist to put any scenario of danger from off planet beings and attribute the human mind set of conquer, rob, to other species in pure imagination. The reflex of our brains to try to make sense out of a cloud and put the jumble of what we see into something recognisable and familiar.-------We in America see a human face in a full moon, the Chinese see a rabbit.
I feel the threat to earth may be the spoors that are encased in the space dust that filters in, these are alian to our planet and could be a threat. The Robots we sent to Mars may in fact carry some bacteria from earth that could change that planet after a thousand years.
Hard to imagine for me that God duplicated Earth thousands of times and sat back to watch evolution take place and all results were the same on each planet.
