Let’s get this started by establishing some basic, incontrovertible facts about the universe we live in. I expect people to disagree with me on a lot of things, but if you don’t accept the following then you and I live in fundamentally different realities, and unless you are very willing to adjust your reality, you aren’t going to like it around here much. This was almost an 11 point list, but I decided not to include a couple of things that might require some convincing. This is really the uncontroversial stuff:
  1.  The universe began sometime around 14 billion years ago (13.75 plus or minus 130 million is the current estimate).
  2. The Earth came into existence around 4.5 billion years ago.
  3. The Earth is an oblate spheroid, which is a fancy way of saying round, but lumpy and bigger around the middle.
  4. The Earth revolves around the Sun.
  5. Life on earth began sometime around 3.8 billion years ago, and evolved over time through a process of random mutation and natural selection from single celled organisms to plants, simple animals, fish, amphibians, insects, reptiles, birds, and finally, mammals and the full proliferation of life on this planet.
  6. The first thing resembling a human didn’t exist until about 2.5 million years ago, and modern humans about 200,000 years ago. So we haven’t been around for very long at all.
  7. Human’s first organized themselves into cities around 5,000 years ago, but there is every indication of thriving cultures creating ingenious tools and symbolic artwork long before that.
  8. All humans first evolved in Africa and migrated outward to cover the world.
