Do aliens exist? And are they visiting earth in spacecrafts?

It would be pretty cool if they were, but an educated guess is no.

Do they exist.....perhaps. The Universe is a very large place and aliens are a very real possibility. Are they visiting Earth in spaceships.......no I don't think so.

The distances involved are nearly incomprehensible and the same Laws of Physics applies throughout the Universe. It is important to remember that we did not "invent" the laws of physics......we discovered them!

I don't know if they do but I think it is very arrogant to think that we are the only intelligent life form. There have been many unusual sightings some of which can't be explained. We always assume they would come in a large space craft but here in Brazil we get some insects that act very strange.

We get large dragonflies that will just hover inches away from our dogs and us. It is almost as if they are studying us. There have been strange sightings further North in the Amazon of unusual lights on several occasions.

There was a documentary made about it.

I think they exist and they've probably found us before we've found them.

Educated guess for me is yes, Tnk about it the Universe is endless. All thats needed to survive (for us) is air land water shelter food,. There has to be a planet somewhere else in the ENDLESS universe that has those traits and an amount of bacteria or substance to create living creatures.

Are they visiting us? Like I said its an ENDLESS universe, the chances of them visiting this world, slim to none:).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
