She can talk at an inhuman rate, regularly repeating what she has said before presumably for emphasis (or perhaps she has forgotten what she said a few seconds before).
Are all MiLs like that?
I suppose that question could be the basis for the foundation of a new topic.

Perhaps I should get out now while the going is good....

The enormous distances between any two star systems would suggest travel (even at light speed) would take years. Who would want to go into space in search of a new planet to populate in the knowledge that you may die on the way, but in the hope that during the journey you might produce offspring who might make it in their own lifetimes.
I think the only reason anyone would do that would be if their own planet was about to be destroyed.

Plus the fact, that at just ten times the speed of light you wouldn't even be able to see the first reflection, even with a telescope, it would be ten years away from its original sighting. What we are seeing when we look up at the stars, is how it used to look depending how far away each star is. They will be all different distances away from us, so the time in the past that we are observing them will vary accordingly.

I think I see what’s trying to be said, but it still doesn’t answer the question does et exist? of course we have no way of knowing for sure, but distant stars have been found with orbiting planets and some have potential to support life, what that life could be is anyone’s guess atm, it’s more likely to be bacterial and not intelligent at all, of course intelligent life has to exist at the same time as we do for their to be any contact, via radio waves, but even then it won’t reach us for many years,

It is quite likely that there is bacterial life on other planets even within our solar system.
More intelligent life having the ability to communicate with us must be at least as far away as 120 light years, as our very first radio broadcast took place (I think) in 1895.
At that furthest distance, any reply from them might not happen for another 120 years.
Of course, a closer civilisation with the necessary technology could well exist but they may not want to communicate with us...
and personally I don't think I'd blame them!

Re: Do extra terrestrials exist.
I concede that it is possible for some basic life to be present on other worlds in the universe. But even planets that enjoy a habitable distance from their sun, we are assuming they contain the same collection of minerals and a suitable atmosphere to sustain life. They must also have the same gravity as Earth to produce similar life. So the exact same size as the Earth will be required. Any larger and the gravity would be too great, and any smaller and the gravity would be less, so heaven knows what creatures would develop on such planets.The chances of exactly replicating Earth are billions to one, and the chances of finding life there that we would recognise as life, is also a billion to one against. Therefore, in my opinion there is absolutely no possibility that we have ever had visitors from other worlds, because those worlds are devoid of any life that could transcend the distances involved, as are we.

Oh yes, of course I've seen them on Star Trek and they seem an excellent idea!
