This is still very long compared to our size vs the size of the universe though. There are an estimated hundreds of billions of galaxies with billions of stars, and they are all very spaced out too. Most stars are significantly bigger than our planet, and our planet can fit over 7.5 billion humans with a lot of extra space. There are 8760 hours in a year, so according to the above humans have existed around 1/4380 of the time the universe has. Meanwhile idk the exact amount but we occupy less than 1/1,000,000,000,000 of the space of the universe.
