Interdimensional Extraterrestrial IE1

Mind-boggling SF action adventure of deep space interdimensional extraterrestrials of another universe who pick up/reply to an SOS message from the Earth, and when their IE1 probe materializes in orbit above the Earth it is shot down by a military space weapon. An IE1 survives the impact and creeps out into the night and a dark forest and hides in a strange place before humans arrive. The army investigates what crashed into the wood, and newspapers report it, and officials at NASA are brought in, and in the end admit a military weapon system shot it out of the sky on its appearance over the world, and scientists explore everything they can to find out what escaped from the crash.
