Gemlady, I'm glad to see that I'm not the only alien here.
My secret is known on a couple aquaria sites along with my leader but I have been walking this earth for 500 years and I can say with some degree of certainty that humanity hasn't advanced all that far and I don't see much hope for the species.
When I mentioned becoming Emperor in less than 28 years in another thread I wasn't talking about the US or Earth I was referring to "galactically". Don't worry, I'll be fair and harsh when I need to be (I love conquest) but the humans of this planet should consider themselves warned. If they don't straighten up by the time I take the throne then I'll turn the planet into slag.
Anyway, to answer the questions:1. Do you think we are alone in this universe?
Absolutely not! The universe to big and it would too arrogant for us to think that we are the only "intelligent" life in the universe. I believe that there are species out there much more advanced than we are and who consider us too "primitive" to interact with. I also like to think that there also more planets that are inhabited by humans that have varying degrees of technology- some more advanced, some behind us.2. If we do find life will it look like us?
We have already found colonies of bacteria on planets in our own solar system but I believe that as our own technology continues to advance and humans from Earth begin to colonize and reach further out into the universe that we will encounter other species of life in various forms- humanoid and other wise. Like I said above I do believe that we aren't the planet of humans in the universe.3. Do you think they have visited us?
I think we have been and I think that we have had visitors for 1000's of years. The reason that we have not had any significant contact that prove beyond the shadow of a doubt that we have been visited is that the aliens believe that as a species we aren't ready for it. Even though we are a curious species we do have a tendency to fear what we don't know or what is different.
