We can talk to people thousands of miles away. The miracles of science are well documented and can be demonstrated daily. We are so accustomed to them that we hardly think of them as miracles. It is not really a case of being open minded or closed minded. Science teaches us to believe in whatever has evidence that can stand up to close scrutiny.
Many sceptics actively investigate miracle claims to see if there is evidence.
For example, James Randi offers one million dollars to people who can demonstrate psychic abilities in controlled conditions. It is easy to think of miracles which can stand up to scrutiny. If I found the original autographs of the Gospels in a drawer in my bedroom, I could hardly write off this miracle as 'hallucination', especially after I had sold them to the British Museum for millions of pounds. There are miracle stories in other religions. There are named eyewitnesses who claim to have seen Mohammed split the moon in two.
