The current NASA estimate is that there are 19,000,000,000,000,000,000,000 stars in the observable universe that are Class G stars like ours AND that have at least one planet similar to Earth. That’s at least 19 SEXTILLION Earthlike planets, folks. No, we are not alone.
The Earth is 4.54 billion years old. The earliest life forms on Earth of which we have evidence appeared between 4.5 billion and 4.38 billion years ago. So, the development of life capable of reproducing itself either takes place extremely quickly in conditions like those on our planet (which seems highly unlikely) OR life here was seeded from elsewhere.
Our sun is 4.603 billion years old. Other stars in our galaxy are on average 3.13 billion years OLDER than our sun. So, most other intelligent lifeforms in the universe are FAR advanced beyond us–billions of years beyond us technologically.
So, where are they, these other lifeforms? Well, my proposed solution to the Fermi Paradox–one that I have not encountered elsewhere–is this: Life that has gone through the singularity looks inward, not outward, and creates its own “interior” worlds to inhabit and explore.
Why haven’t they “officially” contacted us? Well, when was the last time that you tried to establish communication with an amoeba?
