They're lights, but the most beautiful of all. It's as though they're not from the sunshine, but more from the Heaven's. Indian's worshipped them, God's prayed and we admire.  It's unexplainable. The most beautiful, yet natural occurrence that this world cannot explain. Some smart guy might think, "Oh, it's the natural light from the moon and with the humidity in the air, all the electrons from the clouds cause blah blah blah."  These lights don't come from a bulb or even a little candle stick that flickers in the breeze. It's read as a message by the natives, as a sign of beauty and that things will be ok for just once.  It's a sign from God.
