You know as well as I do that no matter how much evidence we show you such as the fact that energy cannot die, there are believed to be multiple dimensions that may exist outside our physical laws, people such as "John of God" have been proven to do spiritual healings that science cannot explain, thousands of people at a time have reported seeing visions of Mary and other apparitions with hundreds of healings taking place during the sightings, people have come back from being clinically dead and have described what went on in the emergency room, and the list goes on and on but most atheists just shrug them aside not even bothering to come up with a logical explanation for them and then continue to push Christians to give them more evidence. You can see the evidence all around you. You claim that Christians can't come up with explanations for your "theories" but the truth is, Christians can and do come up with explanations for absolutely everything you have thrown at us, whether you find them to be acceptable is your problem but I challenge you to find explanations for the list of miracles I have listed above. Until you can explain them with science, you have no credibility claiming that the supernatural doesn't exist.
1) What do you mean by evidence when you say "energy cannot die"? Ofcourse energy cannot be destroyed, its the law of conservation of energy.
2) Multiple dimensions theory fall in the subject of quantum mechanics. I am not an expert in this field but multiple dimension described according to string theory is somewhat convincing. Yet, they still need to make testable experimental predictions otherwise I am afraid it may not be part of science.
3) Have you heard of the explanation of faith healing according to science? Its like this, faith healing may sometimes act like a placebo pill. Belief can at some circumstances create reality. You can see faith healing in other faiths as well, not just in Christianity.
4) By Mass vision of Mary, I think you are refering to the "miracle of the sun". It could be true, because the event has been witnessed by not just one but thousands of people. But it might be just psychological because they were staring directly at the sun for a long time I think. Personally, I think if the mass number of people have witnessed the same event than it could infact be true. But there has been mass miracle in other faith as well, though it might be not as large as the "miracle of the sun", such as the appearing of Koran verse on a baby's skin in Russia and the claimed miracle at Islamberg in USA.
5) When you talk about near-death experience (nde), I want you to think, why does the experience differ among people? Why does the experience differ across culture? Surely, all should experience the same situation right?
Science describe nde like this: when you feel complete peace during nde, it could the result of massive release of endorphins in a dying brain, the buzzing, ringing or other sounds could be due to lack of oxygen in the brain. Many nde experience could be due to electrical stimulation of the brain's temporal lobes, lack of oxygen to the brain in rapid acceleration during fighter pilot training, psychedelic like LSD and mescaline and anaesthetic drugs.
