The most central part of the Earth’s interior would require drilling approximately which is 6,370 kilometers (20,898,950 ft)
The deepest drilling ever conducted in world history is only 12 kilometers (39370,1 ft)
Why is so hard and and is the effort worth it? Or we only will find more rocks ?

In addition to what others have put, the earth can also have voids(holes) which can collapse around the drill(I’ve seen video of these where someone was trying to drill into an earthquake fault line)
