I could fix this world with a little Bisquick, Lysol, and some Duct Tape

In a heated debate last night, we were discussing the realm of technology and how it is encompassing the landscape of a God. Are we really on the verge of immortality? Are bio-engineered nanobots going to race through our bodies killing off germs and mutations, purifying and cleaning our bloodstream, enhancing our muscles, joints, and organs. Imagine a person who is 400 years old, fathering over 20 offspring and living a youthful existance with most of them. Death would be a great adventure only those most daring would take. I would be the most jaded, paranoid, evil person if I lived to be 200 let alone 400. We were never meant to exist forever like this.
Of course, in our argument, I had to "enlighten" them as to their downfall. We are not even a fraction of the way there to anything of what I would call my God's power. And I proved it. Here is my thinking:
Let's take a simple, often never used, example of God's power as used in the Bible. It is told that He knows the number of all the hairs in your head. At any given time. Okay, that's the power we'll use. Small, inocuous, overlooked, and seemingly frail. Who cares? Well, apparently God does or He wouldn't know it. To make things easier on Him, we'll take only living people. Dead need not apply and we don't care how many hairs are on your head and I'm sure you don't care either 'cause you're dead.
So, how could we do the same thing? Can we know the number of hairs on a human head? Every human's head? Hmmm.
1) We'd have to know the exact number of people on the planet at all times.
2) We'd have to know when they are born and when they died at any given time.
3) We'd have to be able to know exactly how many hairs are still living and connected to the skull and growing. Not the ones just hanging waiting to fall off.

Let's tackle this and raise a temple to ourselves shall we? Okay. We'd first need a worldwide number of "biological" satellites in lower orbits which continually monitor life signs for everyone. Capable of discovering new brain waves as well as heartbeats and comparing it to others, these satellites would continually monitor the existance of all human life. These satellites would send/receive information from towers located throughout the planet. The towers would, likewise, send and receive information from microscopic, air-travelling nanobots which we would digest when we breath. A large manufacturing plant in each continent continually produces these nanobots throughout the day and night, flooding our sky with them. Totally harmless, these nanobots would be inhaled in the human body. Once there, the task would be different for some but we'll focus on one particular unit. This unit would travel to the head and extract information. One would be folicules on the human skull. Numbering them and sending the information to other nanobots, the information would eventually travel back to the tower and then back to the satellite. Once there are recorded continuously, the information could be indexed by ethnic, location, age, weight,etc. Basically any way you like. That's it. All that just to count human hairs. How about if we wanted to have a camel crawl through the eye of a needle? That'll be another post.
