The age of planet Earth is approximately 4.5 billion years. You can get a visual sense of how long that is by applying that length of time to a leisurely walk of 75 steps. Not heel-to-toe. Not carefully paced out. Just a simple, comfortable stroll of 75 steps. When you begin, try to select an obvious starting point like a tree or a wall or a car. Those 75 steps will equal roughly 150 feet.

Applying 4.5 billion years to that distance means that every foot equals 30 million years and every inch equals 2 and a half million years.

Current anthropology places the emergence of Homo Sapiens at approximately 130 thousand years ago. On the timeline represented by your walk, that equals a bit less than 1/16th of an inch (or the thickness of 18 magazine pages pinched between your fingers).

Thus, all of the creations, thoughts and inventions emerging from all of Human recorded history - From scrolls to pockets PC's - Dolmans to skyscrapers - Hunting rituals to religions - Clay pots to governments - ALL took place in a stretch of time less than the thickness of a single pixel on a high resolution computer monitor at a resolution of 256ppi. (That would equal 9,765.63 years.) Or,  1/256th of an inch.

Look back to the spot marking the beginning of your 75 steps. Recall, as clearly as you can, the size of the period at he end of this sentence.  (formed by more than 1 pixel by the way) Yes . . . on a cosmic time scale, humanity is much like a gnat in a hurricane.
To apply an even more microscopic lens to this perspective, overlay  a single human lifespan to the timeline.
Some things may be important.
Most are not.
Try to choose wisely.
