Possibly, it depends on one's philosophies and beliefs of others
There are no known alien civilizations in our universe.

In my opinion, yes. There are at least 12.6 million billion or more intelligent alien civilizations in the observable universe.
yes, it is possible to tour the universe.
So far, we know of one planet that has life on it: our own. Anything else is speculation. It is possible there is life - and perhaps civilizations - on other planets; we simply didn't have a good chance to watch other planets, and especially the "extrasolar" planets - from nearby, to either confirm or reject this idea.
It is currently not known whether humans are the only intelligent race in existence. While intelligent life may be relatively rare in the universe, there is no evidence to suggest that it is unique to Earth. In fact, there are many theories and speculations about the potential for intelligent life on other planets, and some scientists believe that it is likely that there are other intelligent civilizations out there. As for why humans may feel lonely in such a massive universe, there are many possible reasons. Some people may feel a sense of isolation and disconnection from the universe due to their limited understanding of its vastness and complexity. Additionally, the fact that humans have not yet made contact with any other intelligent civilizations may contribute to a feeling of loneliness. Finally, the vastness of the universe can be overwhelming and can make individuals feel small and insignificant in comparison. Overall, there are many reasons why humans may feel lonely in the universe, and these reasons are likely to vary from person to person.
no but modern understanding of the universe says this is not possible
at least 12,600 trillion or more. For now, it is unknown.
yes because there are about hundred and hundreds of Galaxy in one universe at least what i read there are hundreds of galaxy so there might other forms if i am wrong pleas correct me :D
The Nile helped them by allowing them to move easily to other civilizations.
There is absolutely know way of knowing. So far we only intelligent civilization that we know of is our own. We have no idea of how common life is in the universe, let alone intelligent life. The number is probably too high for the observable universe. If there are 12.6 quadrillion civilizations in the observable universe of 100 billion galaxies, that gives us an average of 126,000 civilizations for an average galaxy. Since our galaxy has more stars than most that would suggest that there are several hundred thousand civilizations in the Milky Way, perhaps over a million. Suggesting so many civilizations exist in our galaxy would invoke the question of Fermi's paradox: where is everybody?
They introduced the silk road to other civilizations by trading.
