Look, even with our newly-advanced technology, there is still so much we have not found on our own planet. For one thing, new living species of arthropod continue to appear all the time. Then there is that recently discovered extant tapir in the Amazon Rainforest from a few years ago. A similar scientifically unexplainable phenomenon happens in behaviors, like this thing I saw on television one time of a recent heist in Ethiopia, where weirdos tried to kidnap a little girl and the police were on their trail; suddenly a group of lions showed up and drove the creepers off and miraculously did not harm them little girl; in fact, they stayed with her until the police arrived (what I speak is true). Science is used to explain so much, but sometimes it has been proven that it cannot explain everything, by the way.
You think too restrictively. Fact may be important, but it has limits. Imagination, however, has no limits.
