What gives Earth the perfect temperature to live in?
It is neither too close or too far from the sun so it doesn't get too hot or too cold.

(ex: One day on mercury lasts about 58 Earth days! Imagine having daylight for 29 days, and being stuck in the dark for 29 nights!)

Wht makes Earth's atmosphere perfect for us to live in?
Earth's atmosphere gives us oxygen we need to breathe.
The atmosphere also provides some protection from harmful UV rays from the sun. (otherwise we would need SPF1,000,000 sunscreen to not get sunburned to a crisp!)
The atmosphere traps heat from the sun the way a greenhouse does, or like a blanket keeps us warm at night, or our insulation in our house keeps our house from getting as cold as it is outside. Without the extra heat Earth would be too cold to live.
