One Life
This site shows 3 things:
1. How many weeks a human Life has.
2. Why some of what you carry was never revised.
3. What else the same weeks could hold.
The counting is yours. The site only does the math.

Your Life in weeks
A human Life lasts about 4,000 weeks
That is 77 years. Below, each dot is one week. Set your birth year with the slider. Grey dots: weeks already used. Empty dots: weeks still ahead of you.
Revised
Everything gets revised. Some books never are.
Your phone asks to update itself with every generation. You never update your own operating system.
The floppy disk, and those music players, all gone. None lasted fifty years.
Find one new planet and every textbook on Earth is reprinted.
Every coastline on every map was redrawn the moment it was measured better.
The age of the universe has been revised more than once in a single lifetime. Nobody defended the old number.
A drug that fails its trial is pulled, however loved.
Books written centuries ago — not one line changed.
Everything above was changed as soon as a better measurement came in. Some books are never even questioned for revision.
What varies isn’t the teaching — it’s who surrounds you.
Surrounded by people who keep it, you keep it. Put the same faith where few keep it, and most let it go. Pew Research Center, 36 countries, 2025
With an obese friend, you stand a better chance of not seeing yourself as obese — while becoming one. NEJM, Framingham
Pick a faith on the left to see where it holds.
Proven
What is proven
1. You exist, right now. You are reading this sentence — no other fact comes with better proof.
2. The universe is 13.8 billion years old. Measured 3 separate ways: the light left over from its start, the age of the oldest stars, and its expansion speed. All 3 give the same number.
3. All Life on Earth is one family. Fossils show the sequence, DNA shows the relation, geography shows the spread. All 3 draw the same family tree.
4. Your experience runs on brain circuits. Anesthesia interrupts them: you stop — no thoughts, no time, no you. Everything you believe stops with you. Your heart keeps beating; your body stays alive without any of it. Drug clears, circuits reconnect, you and all of it return. Everything you have ever experienced runs on those circuits. Nothing beyond them has ever been measured.
Never demonstrated
What was never shown to be real
1. An afterlife. About 110 billion humans have lived and died. Confirmed reports back from any of them: zero.
2. Prayer changing outcomes. The largest test ever run — 1,800 heart-surgery patients, 2006 — found no effect. Patients who knew they were being prayed for did slightly worse.
3. Prophecy. No prediction from any doctrine that was specific, dated, and checkable has ever come true when checked.
4. Miracles. Every investigated case has ended the same way: a story, a coincidence, or a trick. No exceptions found so far.
The ages
The ages, side by side
Universe 13,800,000,000 years
Earth 4,500,000,000 years
Humans 300,000 years
Oldest religion still practiced about 4,000 years
Your remaining time —
Every doctrine was written by people who did not know the Earth is round, did not know other continents existed, and could not have imagined a plane crossing an ocean or GPS finding a phone within meters. Their explanations froze at that level of knowledge — and are still taught today, word for word.
Today your plane lands and your GPS finds you because exact, testable knowledge works.
Your past has no return. But the remaining weeks of your own Life — those you still control.
Forgotten gods
18,000 gods so far
Humanity has worshipped more than 18,000 named gods. Ra, Zeus, Odin, Marduk, Quetzalcoatl — each one had temples, offerings, and believers who were completely certain, for centuries.
The gods disappeared anyway.
2,300 years of clear minds
The thinkers
For 2,300 years, clear minds have written the same conclusion: this Life is the one to live. Tap a name to read one:
"Remain faithful to the earth."
Friedrich Nietzsche, 1883 — stop trading this world for a promised one.
“God is dead” — what Nietzsche actually meant
He wrote it in 1882. It does not mean a god existed and died. It means the idea of God had stopped working — science already explained the world better. There is either Life or god — never the two together. Bring up a god, and you get confused about Life. Nietzsche accepted Life as the real one, and killed the idea of the unreal one. He warned that most people would take a long time to notice. Over 140 years on, it is still coming true.
The circle
You become what surrounds you.
Choose that carefully — it is your one Life.
When one partner stopped smoking, the other’s chance of smoking fell by two thirds. When a friend stopped, by a third. Whole groups quit together. NEJM, Framingham, 12,067 people tracked 1971–2003
