SUPPOSE WE DRAW A LINE ON EARTH SURFACE,IT IS CALLED STRAIGHT LINE,,BUT MY QUESTION IS EARTH IS ROUND SO WHEN WE DRAW THE STRAIGHT LINE ,IS THAT LINE CALLED STRAIGHT OR CURVED?
IF CURVED THEN WE HAVE NO CONCEPT OF STRAIGHT LINE,WHY?
AND THE MAIN FACT IS THE NEWTON'S FIRST LAW IS WRONG...??????

No the point is precisely the opposite
In physical reality a perfectly straight line is impossible there will always be some tiny fluctuation if just from gravitationa

A perfectly straight line is a theoretical mathematical construct live an infinitely small point.
In physical reality a perfectly straight line is impossible there will always be some tiny fluctuation if just from gravitational effects.
But even mathematically a line drawn on a sphere is not straight in 3 dimensions - clearly look at it from above
It might have a projection in 2 dimensions which is stright though

Because it's against the rules.

If you draw a line as straight as is practically possible on a curved surface then in three dimensions it will be curved. But in local terms the curvature disappears in the "noise" of not having anything perfect. Perfection is a concept only.
We can conceive something perfectly straight, and we can understand we are unlikely to find this in practice, even light will bend.
As others have mentioned, you appear not to go logically from this issue of straightness to Newton's laws. If there is a connnection we have not spotted then you will need to give us more details.
