Earth witout human beings

An absolutely smashing article, discusses at length, what-if human beings (all 6.5 billion) of us were to disappear suddenly? How long would the earth have traces of our being here. Will a future alien race or a future species of earth based animals, provided they are intelligent enough, be able to discover traces of us? If yes, what?
The last few lines of the article aptly sum it up:

"Finally a brief, century-long pulse of radio waves will forever radiate out across the galaxy and beyond, proof - for anything that cares and is able to listen - that we once had something to say and a way to say it. But these will be flimsy souvenirs, almost pathetic reminders of a civilisation that once thought itself the pinnacle of achievement. Within a few million years, erosion and possibly another ice age or two will have obliterated most of even these faint traces. If another intelligent species ever evolves on the Earth - and that is by no means certain, given how long life flourished before we came along - it may well have no inkling that we were ever here save for a few peculiar fossils and ossified relics. The humbling - and perversely comforting - reality is that the Earth will forget us remarkably quickly."

A thought provoking article, to say the least! Rarely am I so mesmerised by an article. Kudos! Read it here!
