do aliens exist, if so would they be similar to life here on earth?

Could life on other planets only be the cellular life forms we have on earth, or could they be an entirely different thing?

do they even exist at all?

    Environmental conditions would be vastly different on other life-supporting planets so evolution would follow a very different path to here on earth...

    Of course, they exist and have been to this planet in the past.  They taught the Egyptians how to build the pyramids of Egypt, the wheel and fire,  The also helped design the anicent city of Damascus. But have not returned since then.

    They might exist, but there is no reason WHY they have to be humanoid like us ar exist AT THE SAME Time as WE do. 2 to 3% of UFO and USO sightings are never explained, including those UFOs over Washington D.C. in July 1948 before the political conventions in August. Why did Eisenhower and Congress turn a Congressional advisory committee into a civilian federal agency, NASA in 1958. Obviously every president and vice president since Truman and many members of Congress do know what really happened.
