Why does an object is attracted towards Earth according to Einstein?? I only know that celestial objects are attracted due to curve made by another massive object but what happens in case of objects attached to Earth??[emoji26] [emoji26]

Gravity is curvature of spacetime. That's true whether the source of gravity is a star or the Earth or you. The "strength" of curvature is different in each case, but the idea is the same.

So u mean to say that due to curvature made by Earth's mass, we r attracted towards Earth?? Or something else?

Basically. Spacetime near anybody with mass doesn't obey the rules of Euclidean geometry. The notion of things moving in straight lines unless acted on by a force is replaced by things moving along curves (towards the Earth) unless acted on by a force - such as the floor pushing up on you. The videos that A.T. posted above are good illustrations.

I think I am much small(15 year old) to understand such physics but I will continue my curiosity [emoji39][emoji39][emoji39]

Just to offer input, Einstein thought of gravity as more of a "side-effect" of the curvature of space time, compared to Newton's view of gravity being an attraction of massive bodies.
