Science isn’t a belief system – it’s a process for finding what’s true.

It starts with observation, questions, and testing. Scientists gather data, look for patterns, and challenge each other’s results. Only when evidence holds up – across time, experiments, and independent review – does an idea become scientific knowledge.

That’s how we know evolution happened, because fossils, DNA, and anatomy all point to the same story. It’s how we know the planet is warming, through direct measurements of temperature, ice loss, and greenhouse gases. It’s how we know the Earth is round – because we’ve watched ships disappear over the horizon, tracked satellites in orbit, and seen our planet in full from space. And it’s how we landed on the Moon – through engineering built on the laws of physics, tested and proven every step of the way.

Science doesn’t claim certainty – it earns confidence through evidence. It questions, corrects, and builds. And that’s why, when science agrees, it’s because reality has left no room for doubt.
