Sea sponge found on Mars by Curiosity rover

On September 2014, Scott C. Waring has discovered a perfect spherical-object on the surface of Mars. According to him, the round object will be an ancient fossil of a sponge. What is it?

Ufologist explains:

Now please don't be deceived by the simplicity of this object. Sure it is round and sure it looks like a ball, but it is 100% proof that life once existed on Mars. This round object is an ancient fossil. It is a sea sponge and very common on Earth. Compare the close up of the Mars ball and the Earth ball. You will notice an incredible similarity in their size, shape, and even indentions. This is hard core evidence that ancient oceans teaming with life once existed. SCW
