Life on Earth

If there was life on a far away planet, and they had the ability to watch over Earth day in and day out.....

Would they think that the planet Earth was inhabited by creatures that looked something like this?

And if they believed that, would they assume that this blue planet had a parasite problem?

I think about this quite often. Seems I have far too much time on my hands. Too bad I don't use it for something productive....
