You cannot witness someone else’s subjective experience.
Again if eye witnesses are admissible in court. And that is considered evidence. Then what source can you quote to prove eye witnesses are not considered evidence? Further more, let me quote about evidence, just so you know for the future:
"DIRECT AND CIRCUMSTANTIAL EVIDENCE
Evidence typically falls into two broad categories. Direct evidence is evidence that can prove something all by itself. In California, jurors are given the example of a witness who saw that it was raining outside the courthouse. Jurors are instructed, “If a witness testifies he saw it raining outside before he came into the courthouse, that testimony is direct evidence that it was raining.”9 This testimony (if it is trustworthy) is enough, in and of itself, to prove that it is raining. On the other hand, circumstantial evidence (also known as
indirect evidence) does not prove something on its own, but points us in the right direction by proving something related to the question at hand. This related piece of evidence can then be considered (along with additional pieces of circumstantial evidence) to figure out what happened. Jurors in California are instructed, “For example, if a witness testifies that he saw someone come inside wearing a raincoat covered with drops of water, that testimony is circumstantial evidence because it may support a conclusion that it was raining outside.”10 The more pieces of consistent circumstantial evidence, the more reasonable the conclusion. If we observed a number of people step out of the courthouse for a second, then duck back inside, soaked with little spots of water on their clothing, or saw more people coming into the courthouse, carrying umbrellas, and dripping with water, we would have several additional pieces of evidence that could be used to make the case that it was raining. The more cumulative the circumstantial evidence, the better the conclusion.
Most people tend to think that direct evidence is required in order to be certain about what happened in a given situation. But what about cases that have no direct evidence connecting the suspect to the crime scene? Can the truth be proved beyond a reasonable doubt when all the evidence we have is circumstantial? Absolutely.
Jurors are instructed to make no qualitative distinction between direct and circumstantial evidence in a case. Judges tell jurors, “Both direct and circumstantial evidence are acceptable types of evidence to prove or disprove the elements of a charge, including intent and mental state and acts necessary to a conviction, and neither is necessarily more reliable than the other. Neither is entitled to any greater weight than the other.”11
Juries make decisions about the guilt of suspects in cases that are completely circumstantial every day, and I’m very glad that they do; all my cold-case homicides have been successfully prosecuted with nothing but circumstantial evidence.

Above quote from “Cold-Case Christianity: A Homicide Detective Investigates the Claims of the Gospels” by J. Warner Wallace"
J. Warner's professional investigative work has received national recognition; his cases have been featured more than any other detective on NBC's Dateline, and his work has also appeared on CourtTV and Fox News. He also appears on television as an investigative consultant (most recently on truTV) and had a role in God's Not Dead 2, making the case for the historicity of Jesus. J. Warner was awarded the Police and Fire Medal of Valor "Sustained Superiority" Award for his continuing work on cold-case homicides, and the CopsWest Award after solving a 1979 murder. Relying on over two decades of investigative experience, J. Warner provides his readers and audiences with the tools they will need to investigate the claims of Christianity and make a convincing case for the truth of the Christian worldview.
(disclaimer: I don't believe we can prove most things. Most facts cannot be proven, most science cannot be proven etc. However I believe that some things can be proven. The universe had a maker. We all accept this, or the alternative is that the universe made itself, spontaneous generation was disproven 100 years ago, thus there is only one option. The universe was created. Now the thing that created the universe, must according to cause and affect have intelligence, and be rational. It must also contain any positive character traits, self sacrificial love etc. Things that are not explained by herd instinct. Herd instinct accounts for some morality, but not self sacrificial love. A wolf may gather food for the rest of the pack, but not at it's own demise, it will most likely eat first, then get it. Humans on the other hand have been known to sacrifice for others. This type of love has no natural origins. Thus the one who created the universe must have that type of love, in order to create it in it's creation. The only thing that resembles a loving creator that is intelligent and rational. Is the Christian God. This to me is proof.
