Ok kiddo, so sometimes when you look outside in the morning, you might see something called a "false sunrise". It's called that because it looks like the sun is rising when it's actually not.
See, the Earth has this big invisible blanket around it called the atmosphere. It's made up of different layers of air and gases. Sometimes, when the sun is really low in the sky, it's light can get bent or curved as it passes through the different layers of the atmosphere.
When this happens, the light can create an illusion that makes it look like the sun is rising before it's supposed to. It's like when you look at a straw in a glass of water - it looks like the straw is bent because of how the light is refracted (bent) as it passes through the water.
So, that's why we call it a "false sunrise" - it's just an illusion caused by the way the light is bending in the atmosphere. Pretty cool, huh?
