Our universe just celebrated its 13.8 billionth birthday. Our home in that vast universe, planet earth, is about 4.5 billion years old. The earliest evidence of primitive life in this home dates back about 3.5 billion years.
50 million years ago our planet was already a beautiful ecosystem; everything was there: mammals, fish, reptiles, birds, flowers, rivers, jungles, clouds, everything. Except for humans…..
Homo sapiens appeared some 350.000 years ago. How fast have we as a species evolved and where will we go from here?
