I can.

While life and aliens could exist on other planets, it is highly unlikely that it can travel here. The primary reason for that is the age of the universe and how long ago life would have existed on other planets.

In so much time, even space exploration at a fraction of light speed would have ended up colonizing every possible planet that could support life, and even with the technology we have now, many that could not naturally.

Even just 1 species 10 billion years ago that started exploring space, would have spread out exponatially, and would have been here before humans even existed.

There would certainly be many species if you just base everything on logic/math/statistics so there must be a reason why that is not the case.

Could be things that prevent space travel beyond solar systems or galaxies that we do not currently know. Could be intelligent life is limited by a certain factor and therefore localized to a planet or a few planets far away from each other, could be many explanations.

The most likely reason though is there is either no other intelligent life in the universe, or, there is something that prevents intelligent life from escaping it's local area of space.

Either way, no UFO's here, no aliens visiting etc.
