Lenticular clouds
Saucer- shaped clouds usually form at high altitudes, and these are called lenticular clouds. Lenticular clouds can be separated into altocumulus standing lenticularis (ACSL). Due to their shape, they are often mistaken as Unidentified Flying Objects, (UFOs).
Since no humans have visited Mars, it is unsure. But Mars is often mistaken for UFOs because of how bright the planet is.
That would be impossible to say. There are more UFOs that are mistaken identity than actually faked.
The type of cloud that is lens-shaped is called a lenticular cloud. These clouds typically form over mountain ranges or other geographical features where airflow is disrupted, creating a wave-like pattern. Lenticular clouds are often mistaken for UFOs due to their distinct, smooth, and saucer-like appearance. They can indicate strong winds at high altitudes and may also produce precipitation.
In earlier times I'm sure it was quite common. They didn't have the advanced equipment that we do today. Now however, scientists identify meteors long before they can be seen from Earth.
Where humans and alcohol are, UFOs will be.

Since UFOs are unidentified, it is unknown what is inside of them.
