Biological life in some form seems to have existed on this planet for most of its existence through various conditions. Life will most likely exist on this planet earth for as long as the sun continues to provide the right conditions i.e., for several billions of years.
Imagine there still are intelligent beings alive on this planet in a billion years who realize they are alive and share information. And always are from now until then, one learning from the other.
Now imagine you could help to make this possible. Is there a greater ambition?
