Space is very cold. It’s -270something C. The temperature on Earth is much higher. The rays that make it through to our atmosphere bounce off the ground, warming it up from the bottom up. That’s why you need a jacket when you climb up a mountain because it’s getting colder the higher you go. Imagine a mountain higher than anything we have. Eventually, you’ll get to -50 C.
