Since the news came out that Mars had water 2 billion years ago, I wonder if Earth is following a similar path as Mars. Could Earth be like the current Mars in the far future?

No I don't believe so. Mars does not have enough mass to have retained its atmosphere, without which it has become very cold, due to the lack of a greenhouse effect, which retains heat close to the surface of a planet. Any water on its surface has frozen solid. If anything our greenhouse effect is becoming more pronounced due to our activities and we may end up like Venus which has a "runaway" greenhouse effect

No, it's what the Earth would look like if it has no atmosphere. But I think Venus is in certain way the past of the Earth because like 3 billion years ago (note: the Earth has 4.5 billion years and life appeared like a million years ago) the earth had a continue acid storm (like Venus does now) that created the oceans and many other things. In fact the soil of Venus hasn´t been seen because it's covered by green acid clouds.

Not exactly. The water thing is still conjecture, since no one has been there. Mars is where Mars is and Mars is the size of Mars. If anything, we could turn into another Venus.
