If you mix oil and water, the tendency of the oil is to float above the water. This happens because the density of the oil is much lighter that the density of water. Any material that has heavier density compared with the water will sink and vice versa.

The above is correct but, this is important "Like dissolves like". Water has very strong hydrogen bonds and tends to 'clump' together. Oils, on the other hand, have a different 'clumping' force (London forces). So oil and water are not at all alike, even if oil had the exact same density as water they still would not mix (they would not be miscible).
There is emulsification but that is a separate thing.
Oil and water can be effectively mixed in cosmetics by using emulsifiers. Emulsifiers are molecules that have both hydrophilic (water-attracting) and lipophilic (oil-attracting) properties, allowing them to bind oil and water together. This creates a stable mixture in which the oil and water do not separate.
When oil and water are mixed together, the oil rises to the top because it is less dense than water. Oil and water do not mix well due to differences in their chemical properties, resulting in the oil forming a separate layer on top of the water.
Oil and water mixed together is called an emulsion. However, since oil and water do not easily mix due to their different chemical properties, the emulsion will eventually separate into distinct layers.
Liquid mixed with ochre can vary, but commonly water, oil, or egg are used to create paint or pigment. Water is often used for watercolor painting, oil for oil painting, and egg (as in egg tempera) for traditional painting techniques.
Oil is not as dense as water. So, even when they are mixed, the water molecules can still slide down in between the oil molecules, thereby causing the oil molecules to form a layer on the surface of the water.
they cannot be mixed unless some complex nano science is used which has not happened till now
Water is heavier than oil. Oil floats on water.

Not a lot, water and oil don't mix and so the oil will float on top of the water.

Water mixed with oil? Oil mixed with water? White smoke out of tailpipe? Lack of compression on 2 adjacient cylinders?
Because of different densities; being density of oil lower than water density, this makes oil float on water
The oil and water will separate into two layers with oil as the top layer.
Oil and water do not mix, however, when they are stirred or mixed thoroughly the particles of oil will become too small to see.
A gel with high viscosity is obtained.
