The comparison to flat earth is a comparison to clinging to what we know and not entertaining what is possible.

I'm not assuming that its impossible, just very unlikely by the sheer vastness of space, the amazing distances between galaxies and more importantly how up until this last 100yrs our planet would not have been a standout in any way.
But of course, I have a very open mind to the possibilities, I just hedge my bets on what I think based on astro physics and what I've learned about the universe.
We are all ultimately guessing at something we know nothing really about, since until we meet an alien race we cannot truly know anything. But its fun to think about

OK. As long as you're sure about that. I'm saying that there's no reason why they couldn't look quite similar and if they did, there;'s no reason why they couldn't assume a form that would reduce the shock.

True, just depends on how much they fear us and our unpredictable nature, as if they have been watching these last 100 yrs they would probably deal with us very carefully

Well that's a nice theory, but if you look at our evolution you'll see that it hasn't come anywhere close to that. yet we have the capability to destroy ourselves and most of life on earth. And some would even have you believe that there are people out there trying to do just that.
So no, technological brilliance hasn't gotten us any nearer to (as JL put it) A Brotherhood of Man.

We are at a very young state in human development, I mean the start of the real human growth is only in the last 100yrs. It will be pretty amazing how much we advance in the next 100 years and when the nano age is in full swing it will make the computer age seem stone age-ish.
Its just a theory, I think the further we move away from mysticism and what our current planet is all about, more into science, logic, reason, etc.. The less reasons we have to kill each other and destroy this planet.
But of course as we advance we will learn new and exciting ways to destroy ourselves.
