I love astronomy stuff, not an expert at all, but have always been so fascinated by it. I am totally baffled by how we seem to claim that we can approximate how long the sun has been around. Like the margin of error for a number like that is crazy…. totally incomprehensible to me. Say that we are 25% off, that means we are over 1 billion years off. So, how do people confidently claim that the sun is 4.6 billion years, rather than 3 billion or 10 billion?

we know how large the gas tank is and we know how much gas is left. we also know the rate of fuel being burnt. doing the math we can figure out how much of the gas has been used and so know how long the fuel in the tank has been burning. we also know how long the tank will last until we run out of gas.
unfortunately the universe is so big that we may not reach a refueling station in time before we run out. its like a tesla and a charging station.
