Is that the reason you asked for help ("help me please")?
Well, anyway, I'll try to make you understand the basics which would eventually allow you to make your choice:
1) D7000 is more versatile machine when it comes to handling the old lenses, such as Ai/AiS (manual-focus-only lenses from the "analog era", good optics, robustly built, but void of electronic circuits) and autofocus with (AF-D version) lenses that do not have their own motor drives; D7000 is slightly better built than D5300 (more metal, less plastic)
2) D5300 is equipped with the newer electronic system, which, among the other things means more connectivity (wireless) options; D5300 is equipped with the rotating LCD (just like D5100 and D5200), which might be very useful in some situations (shooting over different barriers/obstacles such as fences, crowds of people, walls...where you have to stretch your hands high above your head, or when you want to shoot from down-bellow position, like when you're taking photos of insects crawling on the floor etc.)...
Other than that, there are minor differences (to my opinion), regarding the sensor and the button layout etc..
So, my suggestion is: if you are up to buying a DX format Nikon camera with superb quality of photos, and ability to autofocus with lenses that even do not have built-in motor drive (but depend on camera's drive instead), go for D7000.
If you want to have more connectivity options (built-in GPS and wireless), and you will be using only (or: mainly) motorized AF lenses, go for D5300.
