The Fermi Paradox: Are We Alone in the Universe?

I'll counter with this video:

The Fermi Paradox and Rare Earth theory convince me 100%

And they are a proof of the godly creation of humans in the image of god.

Fermi Paradox

-There are billions of stars in the Milky Way similar to the Sun.

-With high probability, some of these stars have Earth-like planets in a circumstellar habitable zone.

-Many of these stars, and hence their planets, are much older than the Sun.

-If the Earth is 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.

-Since many of the stars similar to the Sun are billions of years older, Earth should have already been visited by extraterrestrial civilizations, or at least their probes.

-However, there is no convincing evidence that this has happened.


Rare Earth hypothesis

In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the emergence of complex multicellular life on Earth (and, subsequently, intelligence) required an improbable combination of astrophysical and geological events and circumstances. The hypothesis argues that complex extraterrestrial life is a very improbable phenomenon and likely to be extremely rare. The term “Rare Earth” originates from Rare Earth: Why Complex Life Is Uncommon in the Universe (2000), a book by Peter Ward, a geologist and paleontologist, and Donald E. Brownlee, an astronomer and astrobiologist.

Good read:

Are we meant to be here? Anthropic Coincidences and the Multiverse.

I don't believe so. I think there's something to all the UFO reports, the ancient myths and the various blurry images that people have taken since ... Well, at least the dawn of the term "flying saucer".

I'm not sure I buy the Navy's tictac videos, I'm leery of them suddenly coming out and declaring that the phenomena is worthy of investigation.

I suspect that there are multiple dimensions and, like Jacques Vallee writes, UFOs might be mostly inter-dimensional phenomena, though I don't discount FTL alien craft as a possibility either.

As far as "why are they not landing on the Whitehouse lawn" type questions, I think it's quite clear from what the video/photo evidence suggests, that they aren't keen on revealing themselves.
Maybe their existence would have profound consequences for our own natures - maybe we're more connected to things, in ways that we have lost knowledge of, that their explicit presence would awaken?

There is no way we are the only life form in the entire universe. Also, UFOs would never have living beings in it. Any space traveling civilization is smart enough to build space probes/drones. Which make exploring space a lot easier because you don’t have to keep the “people” on board alive. Why would any aliens visit earth? We don’t have anything unique on this planet. All the minerals, deposits, resources we have can be abundantly found throughout the universe.

VERY VERY GOOD Lecture

This is not say there is or is not alien life but consider this.

How far is life on this planet detectable? The furthest radio waves have traveled from earth is a mere 116 light years, beyond that point we are invisible. The observable universe is 93.000.000.000 light years. Looking at the stars and saying we don't see anything doesn't mean much for we look into the past the further we look out, at the edge almost at the beginning. And then there is the universe beyond that horizon which could be infinite and we can never ever communicate with it.

Furthest humans have traveled is 1 light second lol. I am not surprised at all that if there is intelligent alien life we don't (can't) see it.

Yeah.
