I have found an ancient statue covered in the ground. I am from Haifa, Israel. There are no old buildings nearby. Here is its photo; I don't know what it is!
I would like to know what period this statue belongs to.
This is a marble plinth or capital for a decorative column, likely of Classical Roman origin - the harpies and the immodesty of the subjects particularly give it away. There was a major Roman city nearby at Caesarea.
It will be impossible to give you more information over the internet - your best bet would be to report its discovery to the Antiquities Authority. They'll give you credit for its discovery (a big deal! I'm jealous), and they'll be able to tell you more about it. You probably qualify as a collector, so you'll get to keep it, tho they may request to borrow it for study or display in a museum (A really big deal!).
Congratulations on your find.
