It is said that the light of sun takes about 8 minutes to reach earth:

This means that for light to reach sun from earth it should take about the same time. But is that really true? Shouldn't the time needed be zero and instantaneous? Think about it..., if there is a lamp as big as the earth or bigger than the sun located at earth and points toward the sun, if you switch it on, isn't it obvious that it takes no time for the light of that lamp to hit the sun? Plus one can also simulate this on a desk in your room - make a miniature model of sun and one for earth that is equivalent to real life ratio and place them in a way in which the distance between these two models is also identical to the ratio of real life. Now place a flashlight at the location of the little earth and point it directly at the sun model, then switch it on, isn't it obvious it takes no time for that light to reach the sun? Is it possible that the scientific finding about speed of light is wrong...? Now lets say the size of the source of light is not that crazily big but real life and small. If it does take 8 minutes for light to reach sun from earth from that flashlight in your hand as you stand outside during the day and point the flashlight directly at the sun in the sky, while it takes no time for light of a light source that is humongous to travel from earth to sun, does this imply that speed of light varies with the size of the light source? That the bigger the light source the faster its light travels?
