Here are the calculations on the size of the possible know universe.
I am not saying i don't believe there is life out there because by the law of averages there must be. What i am stating is that i don't think ET has visited Earth.
By your statement that other ET civilizations could be "Millions of yours more advanced that human's" that would also mean that those civilizations could have died out millions of years ago also.

Sorry forgot to add link on size of universe. Here :-
en.wikipedia.org...
Size
The comoving distance from Earth to the edge of the observable universe is about 14 billion parsecs (46 billion, or 4.6 × 1010, light years) in any direction. The observable universe is thus a sphere with a diameter of about 28 billion parsecs (93 billion, or 9.3 × 1010, light years). Assuming that space is roughly flat, this size corresponds to a comoving volume of about 3.5 × 1080 cubic meters. This is equivalent to a volume of about 410 nonillion cubic light-years (4.1 × 1032 cubic light years).

Yes i read it. You can only quite the size of the observable universe because that's all we have to go on. What may be beyond that is pure quess work. It may end at 93.1 light years or go on much much further. Who knows.

So you think we are being visited by ET? Show me the proof. And i don't mean You Tube Videos of lights in the sky that could be anything. I am willing to accept what you say if you can provide REAL evidence.

And what 2000 year old fairy tale would that be?
There is no onus on me to prove anything. You are the one who reckons we are being visited by ET.....but without a shred of proof to back it up? Was you there when the ancients where painting these "ET" murals? No i thought not. Yet you tell me they where painting evidence of ET visiting Earth. Oh dear .

As i have already stated, the probability of life elsewhere is a very strong possibility and it's one that i subscribe to. However.......i don't believe that ET's are flying around or landing/crash landing on Earth. The odd's that they have found us are too great.
