Let me tell you the history of evolution (roughly) for both trees and people based on current scientific models extrapolated from known fossil records.
About 4 billion years ago a simple self replicating molecule formed in the primordial oceans called Riboneucleic Acid. It reacted with elements in the water to create flawed copies of itself. Most of these copies were destroyed by the elements or were unable to continue production, however some continued. Some of these began to have sections that reacted with certain inorganic compounds to create proteins and a protective phospholipid layer around the molecule. This basic structure is what exists today as the nucleus of the cell and the ancestor all modern life. At this point almost all life used methane for energy, however some also metabolized naturally forming sugars. A certain one of these sugar metabolizing life forms had a mutation that created a new compound called chlorophyll that converted CO2 and water to sugar and O2. These creatures thrived and killed off the methane consuming ones with O2, which is poison to them. By this time certain cells had absorbed, but not destroyed, ones that were of benefit to them, creating Eukaryotic life over a billion years ago, this is the ancestor to all complex life. Pine Tree ancestors and Human ancestors split soon after this with Pine ancestors becoming a type of algae while the human ancestor was beginning to evolve to group up in a multi-cellular life. For the next 750 million - 1 billion years aquatic evolution slowly marched on as animal life began to compete for resources and hunt one another with continually enhancing predatory and defensive adaptations. During this time Pine Tree ancestors were creeping onto land, which until then had been devoid of any life and evolved the modern plant cell wall to allow them to live on land without drying out. The Pine ancestors also began to grow upwards, using the new strengthened cell wall to keep rigid and specializing things like bark, leaves, seeds, etc. Around this time the Human ancestors also came to land in the form of amphibians. This was the time that modern coal deposits formed from dead Pine ancestors that began to cover the ground. with nothing to break them down these trees simply piled up and through time and pressure became the primary fuel source for our civilization. Our ancestors then separated from reptiles and at the time resembled large ferrets, while Pine Trees were more or less it's modern form. Human ancestors spent most of the dinosaur era underground as creatures that resembled small rodents. After the extinction of the dinosaurs our ancestors came out of the ground, began to inhabit trees and evolve into primates. This continued until a shift in the climate in Southern Africa led to the jungle receding and the previously tree dwelling primates on the ground. This group is what we now call the Great Apes. One of these began to evolve to use tools and scavenge for meats, human ancestors, and over the next few million years evolved into Modern Man.
That is how Humans and Pine Trees Evolved. All of this is backed by evidence and a quick google search on any of this can give you it. Have a good day.
