'What-if' an advanced ET were to notice Earth?...

Maybe from our perspective assuming every life forms and intelligence sources from only water or carbon based beings might be too naive. Well many theories suggested about other chemistry based life conditions.

Through diversified carbon molecule dominances there are diversified carbon lab planets likely support different life forms thus diversified intelligence approaches could evolve.

Carbon based life makes more sense, carbon is a common element throughout the universe; sillicon based life is possible, albeit, sillicon is not as nearly common as carbon.

In Egypt in a burial crypt, from the 2000bc era, dug up in the 1880's, on a lintel over the entry door is a carved side view of a helicopter.Who flew choppers then, like 3000 years ago.
And in the 1960/70's a scientist from NASA actually did a bit of research on Ezikiel's "space vehicle" and while it can be built in current times, it cannot be flown because of the lack of a suitable driving force, ie reactor. We are well behind the owners of that vehicle.
Does "out there" matter more than "right under our noses???"

Do some reading on the "helicopter" and you will find out that it is a glyph that got blurred over the ages.

Just a question which may have been posted by others in the past but I'm unaware of since I'm new to this board:

Some of the pulses detected by Astropulse couldn't be caused by EMPs from nuclear wars in distant planets? Obviously one cannot readily differentiate them from other naturally occurring pulses yet they could be an admittedly sad manifestation of intelligent life out there. I don't know what the effective radiated power would be in the segment of the spectrum we are tuning in but I would imagine is quite large.

The distances between stars are to vast, unless those aliens have mastered warmhole traveling, or other exoctic means of propulsion; higly doubtfull that aliens ever visited Earth or ever will. The " what if, or you never know " scenarios simply do not aplly. Lets apply physics and astronomy when talking about ET visiting Earth. Like saying the aliens helped the Egyptians, Astecs, and Incas in building their pyramids, that is called, bad astronomy. Much more probable that SETI will capture ETI radios signals. The identification of habitable planets with life will happen with tools such as Keppler space telescope, and other telescopes.

BTW, my SETI@HOME project just picked up a Gaussian pulse with a score of 4.2....:O

In the 1950'S a guy flying a Sea Fury fighter between Goulbourn and Nowra in NSW Aust took some gun camera film of a "thing" which was clocked on radar, departing the scene at 1400mph, which was NOT attainable by "then" aircraft in service use.
I suppose he had a "vision", like dream at 20,000 feet doing 450mph.
There were 2 of those "things" and they were tracked on a 277 radar site.
I looked at the pic of the things on the lintel, and it looked OK to me, along with the other images. Like the "Varamas"
Are we sure that Ezekiel was a nutter,or do these things??? make a 50 year round trip every 50 years to see how we are doing.
If I were a "advanced" Space guy the last place I'd want to visit would be here.
If you were to imagine what people doing long space trips looked like, they would not be like us. At least 30% of our size, saves space inside vehicles, reduces load levels, fixed populations,no baby boomers, reproduction by cloning, and long sleeps during trips.
We need to start reducing our size, or we will never get off this falling apart brick.
We have about 1 million years before the planet starts rolling about.VBG.

Scanning through Project Bluebook I begin to wonder if we already have. Is it possible the nuclear end to world war two got their attention? In the 1950’s there were enough sightings for the government to investigate with some interesting results. That may be due to media coverage bringing it to every ones attention or it may be there were more sightings so the media reacted but the increase in sightings had another cause. Possibly two large nuclear bursts getting every ones attention? Which is cause and which is effect? I don’t want to rule out either case but I find the timing interesting.

Just like the B17th stealth plane, during its development in the late 70's to 80's, people leaving around area 51 would think that they saw a UFO. Just an earthly plane. UFOs are stuff fantasy, no substance in reality or science.

So what do you consider a basis in reality or science to mean? When an object is both seen by pilots and recorded on radar moving at extreme speed and maneuvering in ways considered to be impossible even in theory, it is by definition an unidentified flying object. Physical and scientific evidence that something was there has been found in several investigations. Are you saying radar and pilot reports are all being faked? Are you saying that the investigators in project bluebook are incompetent, or the evidence they collected fictional? I am certain a large number of UFO reports are fakes or something quite ordinary in our world that is just not understood by the people seeing it. Scientific progress is made through gathering and analyzing data. To class all UFO reports and associated evidence as fiction is not a scientific approach at all. It is very human, but not very scientific.

Repeatable results in a laboratory when possible, absolutely. When not possible then you are stuck analyzing what data you can get. I agree that eye witnesses can be unreliable, but not all of them all the time. The investigators at project bluebook worked with what they had but it was more than just eyewitnesses. Each person must decide which evidence they will accept and which evidence they will not. It is just as unwise to accept everything as it is to exclude everything. If you accept only what can be reproduced under controlled conditions theories like evolution and the big bang theory must be false? Or did they reproduce it and I haven’t heard about it? If you exclude all witnesses as unreliable we may as well stop having history classes in school or prosecuting crimes that were not caught on video. Wait, videos are all fake? I would like to see at least some effort on the part of the scientific community to help UFO hunters obtain more useful data. Most UFO hunters are regular people with cameras. If there has been any effort to help UFO hunters develop equipment that will provide better or more useful data I am not aware of it but I applaud their efforts. My theory is that some of these unidentified objects are alien in origin. I will collect data as I am able and keep trying to prove that theory. If you have a different theory I invite you to do the same.
Between us we can hopefully identify all of them and find out.
