Cpu. Gpu

Why don’t i have GPU in cycles engine?
there is only CPU

I’m using my laptop

you have to have a graphics card that is compatible with blender cycle GPU for it to work
laptops usually only have CPU
i thank you will have to get a tower with a card that is compatible
you can ask what is needed for the GPU

Do you have a supported gpu as described here? If not, your computer is not capable of GPU rendering. It is unlikely that a laptop will have a good enough card.
