I know earth rotates around itself and the sun but what makes it rotate? (Sory for my english not my native language).
In: Earth Science
The mistake in this thinking is that you are used to movement on Earth, not in space. Here on Earth, a car needs to spend fuel to keep moving, because the air drag and tire friction and engine resistance etc. are slowing it down.
In space, nothing is slowing you down. If you already move at some speed and you don’t spend any energy on altering that movement, you will just keep on moving at that speed forever.
So the question you should be asking is not how the Earth keeps rotating and moving, but rather what made the Earth rotate and move in the beginning. And the answer to that is how the solar system formed: Out of a huge spinning cloud of gas, which condensed into small spinning lumps of gas and rock. Earth is one of those lumps, and thus keeps on spinning (around itself and around the Sun) forever.
*) obviously not really forever, and all of this is a simplification, but it should do for an ELI5.
