Maybe so , but only in imagination:
Euclid' s definition of point is : an entity with no parts
Line is a shortest distance between 2 points , and is an entity that has no width or height
Plane has no height.
Volume that has 3 dimension that any substance for existence has to have 3 dimension and occupy space.
Then they go 2 defining edge of 2 volumes make a plane
Edge of 2 planes make a line
Edge of 2 lines make a point.
Then, Descartes a scientist of 18th century brilliantly creates coordinate system that all points of a plane can be specified with 2 numbers which are the horizontal and vertical coordinates of that plane.
In math there are some abstract notions like no part of a point should be accepted as premise, then it took 18 century that come up with a gesture that gives a sense for no point not to be a complete void.
