ET are on Earth now, they have many bases here, also on the moon. they were here first, how long? i don't know. A long time before us.
Only a very small group of humans are in contact or have had contact with them. As far as i know there are multiple species on Earth and visiting
Where they come from exactly is rumored but still uncertain, planetary or inter dimensional?
Firstly they have absolutely no desire to show themselves, they want to remain secret, hidden, they have done this for thousands of years,and will
continue like this. They just keep an eye or monitor us, they have other agendas as well such as abduction, DNA manipulation, experiments etc. They
take humans but their exact reason is unclear to us still.
1) Control the planets development
2) Stop anything that could lead to earths destruction like asteroids, or other devastating effects from space
3) control humanity evolution development,
this is what they do, however i have other theory's as well;
they seem to have an interest in nuclear weapons < probably because of reason no 2), there are some reports of these craft around missile bases.
i think its possible that the first use of these weapons such as Hiroshima, has led to the ETs increased interest, as these dates around the War seem
to link with when the UFO/ET rumors peaked or began. Roswell was when humans made first contact,
