Fermi Paradox:

The Fermi paradox is the discrepancy between the lack of conclusive evidence of advanced extraterrestrial life and the apparently high a priori likelihood of its existence.[1][2] As a 2015 article put it, "If life is so easy, someone from somewhere must have come calling by now."[3]

Chain of reasoning

The following are some of the facts and hypotheses that together serve to highlight the apparent contradiction:

• There are billions of stars in the Milky Way similar to the Sun.[7][8]
• With high probability, some of these stars have Earth-like planets in a circumstellar habitable zone.[9]
• Many of these stars, and hence their planets, are much older than the Sun.[10][11] If Earth-like planets are typical, some may have developed intelligent life long ago.
• Some of these civilizations may have developed interstellar travel, a step humans are investigating now.
• Even at the slow pace of currently envisioned interstellar travel, the Milky Way galaxy could be completely traversed in a few million years.[12]
• Since many of the Sun-like stars are billions of years older than the Sun, the Earth should have already been visited by extraterrestrial civilizations, or at least their probes.[13]
• However, there is no convincing evidence that this has happened.[12]

“Since many of the Sun-like stars are billions of years older than the Sun, the Earth should have already been visited by extraterrestrial civilizations ...”

Some believe that this possibility is the explanation for how some extremely precise structures exist that carbon date older than man. I am inclined to think that Homo Sapiens could very likely be HS v3.0 or so, some version of an experiment in how to develop intelligent life.

FWIW ...

The key flaw in the Fermi paradox is that it assumes that aliens are stupid.

You would have to be stupid to disclose your existence to dangerous and hostile apes.

That is why I call SETI the Search For Extraterrestrial Idiots

Reasoning?

How can something appear. by itaelf, out of nthing, no not anything at all!

How can anything come into existence, let alone be complicated enough to reason??

However, there is no convincing evidence that this has happened.[12]

No proof of an assertion does not equal proof of its inverse.
