People who died for a few minutes and came back to life via medical help have stated, that when they died, that they witnessed a "person" in front of them in total whiteness.
All of these People stated the same thing the person and total whiteness in the background.
When there is a lack of oxygen going to the brain people perceive seeing a bright light, I have never heard of someone seeing a person, but even if they did it wouldn't prove a god exists. I'm a PEARList.
"We swallow greedily any lie that flatters us, but we sip only little by little at a truth we find bitter." ~ Denis Diderot
