Are We From Mars?
News story originally written on January 19, 2000
Did we come from Mars? Scientists say that tons of rocks came to Earth from Mars many years ago. These rocks broke off of Mars when asteroids ran into it.
They say that tiny organisms called microbes were living inside the rocks! They may have landed here and started life.
We do know that there can't be life on Mars now because it's too hot and we haven't found any water. But a long time ago, it was cooler and there was water.
