✦ In plain words

An atheist is someone who isn't convinced that any god exists. That's all. It isn't a religion, there's no holy book, and it doesn't mean having no morals. This site shows the reasons, gently and with evidence, for anyone from age 10 to 100.

How we explain things

Every page starts with a short summary. Switch to Detailed for the deeper context. We keep evidence and interpretation apart, link original sources, and include the strongest replies from the other side. Our illustrations help explain; they aren't evidence themselves.

Simple or detailed? Open Choose Your Path at the top of any page to switch between Simple (short, easy explanations plus the hands-on models) and Detailed, to make the text bigger, or to switch to light mode.

The original texts

Don't take our word for it.

Read. Compare. Investigate.

Every verse reference on this site opens a pop-up with the original Hebrew or Greek, each word's dictionary meaning, and three English translations side by side. Try one:

Genesis 1:6–8 · Isaiah 40:22 · Psalm 22:16 · Matthew 5:17–19 · 1 John 5:7

Psalm 22:16 (Hebrew v.17)
כִּי סְבָבוּנִי כְּלָבִים עֲדַת מְרֵעִים הִקִּיפוּנִי כָּאֲרִי יָדַי וְרַגְלָי
KJV: "…they pierced my hands and my feet."
Hebrew: "…like a lion, my hands and my feet."

One word, two very different readings. This is why the original matters.

  2. Visuals: the moving Earth uses textures from the three.js project's example assets (MIT-licensed repository), derived from NASA imagery. The painted topic and experiment cards are AI-generated concept art, animated in code; they illustrate ideas and are not evidence or photographs. Planet facts: NASA Planetary Fact Sheet and NASA Science: Solar System. Models are illustrations, not to scale. The galaxy count is a conservative figure; published estimates range from hundreds of billions to about two trillion. Universe timeline: first light (cosmic microwave background) ≈380,000 years; first stars ≈100–200 million years (approximate); oldest widely accepted fossils ≈3.5 billion years; Homo sapiens ≈300,000 years (Jebel Irhoud, Morocco).
  3. Flood-story markers on the map are well-known examples (Mesopotamia, Israel, Greece, India, China, the Americas, Norse myth, Aboriginal Australia). Floods are common everywhere, so widespread flood myths aren't by themselves evidence of one global flood. See Borrowed stories.
