Trees.

I live in the Forest of Dean as some of you may remember. I was out in the forest today, looking around at all the trees, I got to wonder, where did they all come from. I know they grow from a seed, but where would the first seed have come from. Or is this another chicken and egg question?

Found this for you though..
//The world's earliest plants were a few centimetres high, consisting of ferns and mosses. The plants werestemless, and the earth's climate was Equatorial. Around 400 million years ago, in the so-called Devonian Period, plants began to form stems, and thus the first stemmed plants emerged. As the plant life adapted and competed for air, the stems grew longer, and by the middle of the D. period, the luxuriant Paleozoic forests spread across the globe, with huge horsetail plains, clubmosses and enormous ferns reaching 100ft high. Conifers "soon" joined them, having eventually evolved to the tree-like structures we know today, with root systems, vascular growth and secondary growth.
To conclude, there was never, so far as we can know, an actual moment when the first single tree suddenly appeared or began to grow. All over the world, lush forests gradually grew, with the first trees as we know them today appearing around the mid Devonian Period, circa 400-350 million years ago. //
