Imagine it this way: you wake in your house with your pets. The bird is chirping in its cage, fish are swimming, dog is scratching fleas, cat is stalking a bug, hamster is hamstering, ferrets are getting into your large hydron coll-…. Roomba.There’s even a goat and chicken in the backyard. Life is good. But as you’re standing outside watering your flowers, watching aphids destroy you vegetables, and avoiding a bee you stop and look around, beyond your yard, into the surrounding neighborhood. It’s quiet. There’s no people out. More than that, there’s no animals! No birds or bugs. There’s not even trees or plants or flowers. While your yard and house is teeming with life…. No one is in your neighborhood. Nothing living, exists beyond your lush green lawn. Odd, right?

You can’t really leave your house to explore so you climb to the roof and start looking around. You see more of the same. Lots of rocks. Plenty of sand. But no life… not even decaying houses to show life was once there. It’s untouched barren land as far as you can see. So you build a some robot friends and send them out to explore for you. They head out of your yard… past your block… beyond your neighborhood… far into the city…. And further still. They travel into the country side beyond the city, into the land that borders your city area. And all they send back is more of the same. Cold rocks with no sign of neighbors, no sign of vegetation, no sign it was ever even there. You’ve figured out approximately how large earth is (theoretically) and you know you still have lots of land to cover …. But you really should have come across even a *sign* of life. A foot print. A dry leaf. Animal bones. Feathers. Soil! water! Fossils! Sea shells! An old Nokia! SOMETHING!…

But your farthest reaching robot friends have reported back from beyond your borders…. Nothing.

So you’re standing in your lush green yard with abundant water and animals everywhere and food growing like crazy and this chaotically diverse buzzing-with-life plot of land that you simply woke up on… and it appears to be the only even remotely living thing for miles all around you… even when you find a chunk of land that has all the same variables as your yard (not too warm or cold, weather just right, etc) nothing appears to grow there, not even weeds.

Why?

Why is your yard the only speck of green in a world of cold non living rock? Your yard can’t be the only thing on the entire gigantic earth with life on it… can it?

Where are all the neighbors?
