recently NASA received pictures from their rover in Mars. none of the 照片 looked odd except one. they looked 更多 into the matter. at first they claimed it to be a simple chemical compound mix making a shape but now they're not so sure. some still claim it to be nothing but others are saying that life has finally been found. in that picture there is 2 rocks and in the middle of them there appears to be a rat. so what do 你 think? life finally proved 或者 a chemical compound making an unusual shape?
