No one knows, but if they are real, they probably just fly, shoot missiles, possibly fly at speeds impossible for mankind to fly at.

Neither aliens nor alien spacecraft are known and proven to exist. In that sense, the answer is no. UFO means "unidentified flying object", not "alien spacecraft". If there are aliens out there on other planets, and they see something they themselves cannot identify up in the air, then in that sense there is an alien UFO.
yeh, alien space craft is done real!

The acronym "UFO" stands for "Unidentified Flying Object", not "Alien Spacecraft". UFO means you don't know what it is, which means you don't know it to be an alien spacecraft! An alien means someone who is from another country. It is also used to mean "person from another planet". So far, in real life, no aliens are known and proven to have come to Earth. No UFO has ever turned out to be an alien spacecraft. It's fun to pretend about such things, but taking it any further than the actual facts is like a carpenter driving nails into air-- not a lot actually gets done!
Safely locked in the imaginations of those who dreamed it up.
Most pictures of UFOs or Aliens are fake. So far, none of the alien photos have been shown to be anything but fake. So far, none of the UFO photos have been proven to be alien spacecraft. For some reason people call alien spacecraft, "UFOs". even though UFO just means "thing in the sky that I don't know what it is".
No. UFOs are proof that some people have seen things in the sky that they themselves cannot identify. That is what UFO means, not *alien spacecraft*. There has never been the slightest shred of evidence that *any* UFO was an alien spacecraft, so the answer to your question is no.
