Science neither confirm nor deny God, ie science is neutral, we know that. Science evaluate stuff based on data, knowledge and evidence, we know that too. And science does not investigate everything ie it is not all encompassing - we know that but many people like to think that it is as good as everything. In fact, there are MANY aspects of our life where we do not use science to confirm – instead we use our senses, intuition, power of observation, faith and probability, which works too.
For instance: Do you always use science to prove human feelings (love, anger, greed, hatred etc). Does someone who is dating another person use science?
Secondly, science does not and cannot explain things in the spiritual realm --but spirits do exist on earth. In your part of the world, America and Europe, you may not see this more than people in Asia (even though some Hollywood movies about true stories of haunting in USA and Europe – but science won't confirm the haunting, ghosts or spirits) .
I will try to keep this true incident brief (and it is only ONE of the many such spiritual things that happen). Many years ago, a close friend at same church was on the verge of death, from a lightning strike. He was the only Christian among his many siblings, and as he laid comatose for a few days in hospital, his family decided to consult the temple medium (a pagan priest) who communicated with spirits. Although our church was not agreeable, however, we cannot stop the family. As the medium called upon ithe spirit, he did something to an ordinary porcelain bowl -- he cast a spell, so to speak. He then threw the bowl on the floor and if it broke, my friend would die, and if the bowl didn’t break, my friend would live -- the medium said. At first throw, the porcelain bowl didn’t break. My friend’s family asked him to throw it up in the air so it would fall from a great height. The medium did, the bowl didn’t break. They requested the medium to throw even high, as much as 15 feet – my friend 's brother told me later-- the bowl dropped to ground and didn’t break. He was asked to repeat the highest throw, but the result was same. After the ceremony ended and the spirit’s presence left, the priest, to show that he did not use a fake porcelain bowl, dropped it to the ground, and it broke into pieces. The family told the church members about what they saw. Although I did not witness the process, however, I am sure they would not lie. They even believed that their brother would live. A few days later, however, he died. The siblings, in a state of deep grief, related the same temple process to people who came for the funeral ie they could not be lying.
Can science explain how the bowl didn’t smashed into pieces when thrown a few times from high during the spiritual process, and after the spirit left, it broke when thrown from a few feet above ground?
Now, this is not the only unexplained spiritual phenomena. There are many in this part of the world. In about 2010, in Singapore, one incident even went to court as the woman, who used to have a snake spirit, sued the Catholic church, blaming them for mental and physical pain she felt after she was exorcised. During the hearing, the priests and church members narrated that the woman could move like a snake on the floor during the exorcism. Can science explain such spiritual phenomena? And there are MANY more such cases in Asia.
Today, we travelled in aeroplanes, sent text messages to people far far away in the blink of an eye, and do gene therapy.... but these do not mean that science and technology have found everything, far far from it. But some people seem to think it has discovered most things, as good as all things or almost everything. When science hasn't discovered God, some people claim that creator doesn't exist because science hasn't confirmed it -- ie going against how science reasons, and making a false claim.
Science does not say non-scientific explanations are unreliable or wrong. But some people say that millions of lifeforms does not mean God created them -- just because science didn't prove it. They claim that life started on its own and evolved beautifully into millions of life : and even though they have no proof, they like to imagine that their hypothesis hold water, which is contradictory to their claim to believe in scientific proofs only.
Some people deny the power of observations, common sense, intuition, probability, process of elimination etc. Does science tell you to do so? Or are you denying your basic intelligence in order to make it more complicated and intellectual? Or you deny the Creator's existence and creation because of personal ANTI-GOD feeling --- that's the truth isn't?
