Snapshot · The Diary Of A CEO with Steven Bartlett
Life on Earth got underway within 100 million years of when it possibly could have — roughly 5% of Earth's total timeline — suggesting the process is swift and likely common across the universe.

Life on Earth emerged with startling speed — within 100 million years of the earliest it possibly could have, representing just 5% of Earth's 4.5-billion-year history. [1] — Neil deGrasse Tyson "Life on Earth began within 100 million years of when it possibly could have — just 5% of Earth's timeline. Scale that speed across 100 bill…" 30:55 Whatever challenges scientists face replicating abiogenesis in the lab, Earth didn't seem to have the problem. Scale that ease across a galaxy where we've already catalogued 6,000 exoplanets in a tiny search radius (first discovered only in 1995, a year before Steven Bartlett was born), and across hundreds of billions of galaxies beyond that, and the non-existence of alien life becomes the far more extraordinary claim. Tyson also complicates the concept of 'intelligent': by raw brain mass, humans rank fourth on Earth behind whales, dolphins, and elephants. The brain-to-body-mass ratio that restores human supremacy only holds among mammals — mid-sized birds like magpies and parrots beat us on that metric too. Aliens prioritising cognitive capacity might skip straight to the whales.
Life on Earth began within 100 million years of when it possibly could have — just 5% of Earth's timeline. Scale that speed across 100 billion galaxies each with hundreds of billions of stars and 6,000 cataloged exoplanets in a tiny search radius, and the non-existence of alien life becomes the extraordinary claim.
As of recording, astronomers have cataloged 6,000 exoplanets just in a tiny search radius around our Sun — first discovered only in 1995.
Animals first sensed light 540 million years ago, triggering an evolutionary acceleration known as the Cambrian explosion within 10 million years.
It is estimated that half of all cortical activity in the human brain is involved in visual function, underscoring vision's central role in intelligence.
Cognitive neuroscience literature shows that by age 6, humans can recognize tens of thousands of different object categories — far more data than early AI systems were trained on.
Only about 3% of FDA-approved drugs have genuinely unclear mechanisms of action, making an unknown mechanism a meaningful early red flag for any compound.
Even compounds that clear preclinical testing often fail in humans: 30 to 50% of drugs entering phase 1 trials do not advance to phase 2, frequently because human behavior differs from animal models.
More than 80% of published BPC-157 research comes from a single academic group whose researchers have IP and commercial interests connected to the molecule, limiting independent replication.
Roughly 100 peptide drugs are already FDA-approved, about 150 more are in clinical trials, and 600–700 are in preclinical development, underscoring the legitimacy of peptide science broadly.
The scientist who discovered BPC-157 refused to disclose the screening method used to identify the compound and has never fully published the parent protein sequence — what Peter Attia calls 'scientific trust me, bro.'
The brain's visual, auditory, and motor cortices light up nearly identically whether an experience is real or imagined, making visualization a form of actual neural training.
