I just heard an amazing story from the father of a friend of mine. He claims that about 20 years ago he was sitting in his car overlooking Lake Michigan when he saw something that he still can't explain.
He was at a popular overlook in Elberta, Michigan and had just finished watching the sun set. The sky was growing dark and most of the other cars had already left.
In the southwestern sky over the lake he spotted a bright green light well above the horizon. It looked like the light was very far away and slowly moving to the north.
He watched the light move for a few minutes as the sky grew dark. Then the light flashed off and on a few times and when it came back on it seemed to be getting brighter.
It was coming towards the shore and it was moving very fast. Then it slowed down and plunged right into the water of Lake Michigan. He could see the light zip away once it was submerged.
Once it had disappeared he jumped out of his truck and went over to the one car that was still parking there. Inside was an elderly man and his wife and they were obviously as confused about what had just happened as he was.
He swears that this is a true story and I don't think he would make it up. So what was it? Strange Meteor? Alien Craft? Secret Government Project? We may never know.
