Ancient patches of a giant seagrass in the Mediterranean Sea are now considered the oldest living organism on Earth after scientists dated them as up to 200,000 years old
Australian scientists sequenced the DNA of samples of the giant seagrass, Posidonia oceanic, from 40 underwater meadows in an area spanning more than 2,000 miles, from Spain to Cyprus.
The analysis, published in the journal PLos ONE, found the seagrass was between 12,000 and 200,000 years old and was most likely to be at least 100,000 years old. This is far older than the current known oldest species, a Tasmanian plant that is believed to be 43,000 years old.
Prof Carlos Duarte, from the University of Western Australia, said the seagrass has been able to reach such old age because it can reproduce asexually and generate clones of itself. Organisms that can only reproduce sexually are inevitably lost at each generation, he added
The separate patches of seagrass in the Mediterranean span almost 10 miles and weigh more than 6,000 tons.

But surely, this can't be so!
The world is only 6,000 years old, don't you know? This is obviously just a trick by Satan to confuse us!
A moss spreading throughout the Hawaiian Islands (map) appears to be an ancient clone that has copied itself for some 50,000 years—and may be one of the oldest multicellular organisms on Earth, a new study suggests.
The peat moss Sphagnum palustre is found throughout the Northern Hemisphere, but the moss living in Hawaii appears to reproduce only through cloning, without the need for sex or production of spores.
All the moss populations sampled share a rare genetic marker, which suggests they're descended from a single founder plant that was carried via wind to Hawaii tens of thousands of years ago.

That is until they breach Vostok!
The Mourning Gecko or Common Smooth-Scaled Gecko (Lepidodactylus lugubris) is a species of gecko. This small (10.5 cm total length), nocturnal gecko feeds on small insects and flower nectar. This species is notable because it is parthenogenic, and there are no remaining males that have been found. Females engage in pseudocopulation, stimulating both to produce viable eggs. These eggs are adhered to surfaces in protected locations. Most clutches consist of two eggs, and clutches are laid two to three weeks apart.

I don't think it's possible for you to be any more confused and lost then you already are. Stop trying to derail a excellent thread with your God bashing. Take your hate to a anti God site you'll be alot more at home there!!
Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.
Cyanobacteria or blue-green algae became the first microbes to produce oxygen by photosynthesis, perhaps as long ago as 3.5 billion years ago and certainly by 2.7 billion years ago. But, mysteriously, there was a long lag time - hundreds of millions of years - before Earth's atmosphere first gained significant amounts oxygen, some 2.4 billion to 2.3 billion years ago.
