It is usually claimed by the atheists and the atheistic scientists that there is no evidence for the existence of God. But it is not true that there is no evidence. Actually the fact is that when any such evidence is offered, it is usually ignored by the atheistic community in general.
It has been shown in the special theory of relativity that both the travel time and the travel distance become zero for light. As per this theory light can travel even an infinite distance in no time, because this infinite distance will be infinitely contracted to zero distance for light, and to cover zero distance zero time will be needed for light. So long SR is not replaced by some other better theory, we will have to accept that its mathematical equations are correct and that therefore whatever conclusions can be drawn from its equations are also correct.
So, light originates within space and time, but as per SR both space and time become non-existent for light. I have shown in two different articles here1 and here2 that whatever may be the cause of it, this cause cannot lie within space and time, because in that case there will be an infinite regress.
Here I will give one more simple reason as to why this cause cannot lie within space and time.
Let us assume that both the light and the cause due to which space and time become non-existent for light exist within the same space and time. So when the cause makes space and time non-existent for light, the cause will also be equally affected, because here both the cause and light exist within the same space and time. So, when space and time become non-existent for light, they will also become non-existent for the cause itself. Thus both the light and its cause will have the same characteristics; both of them will be spaceless and timeless. So if the cause lies within space and time, then we will find in nature one more entity other than light that will have the same properties as those of light. But actually we find none, light is the sole entity in nature that has these properties. That means this cause does not lie within space and time; it lies outside space and time.
Even if we find in nature one more entity that has the same properties as those of light, that will not solve our problem. This is because we will now have to ask the same question about the cause itself that we were earlier asking about light: being within space and time, how do both space and time become non-existent for it? But this is the old infinite regress problem and I have already dealt with it here1.
