There are many tasks that computers do that had to be done by hand before the existence of computers. Tasks such as file keeping, writing, and record keeping all used to be done by hand at home and at one's job.

Before the invention of cars, gasoline was primarily used as a solvent and as a fuel for lamps and stoves.

Before the invention of the mustard gas, was was fought using tear-inducing irritants, while after the invention of mustard gas, war was fought using chemical weapons.
The first commercially available TV was sold by RCA in 1939. It received up to 5 channels (VHF 1, 2, 3, 4, 5 -- we no longer have channel 1 but 2 to 5 are the same). Sales were stopped in 1941 due to the start of WW2. Analog computers of both mechanical and electronic types were available before this. Digital computers of both electromechanical and electronic types were not available until after this. Both were roughly 3 orders of magnitude more expensive than the top of the line RCA TV of 1939 through 1941. The very first invention of a TV was just before WW1 but they were mechanical and not practical to build and sell. The very first known invention of an analog computer was around 100 BC, but it was mechanical. The very first invention of a digital computer was in the 1830s by Babbage, but it was mechanical and he was never able to build it.
well they wrote on rocks or they used animal skin for paper
No. Minecraft is a computer game. The Illuminate fell out of existence longer before the invention of computers.
if by "computer" you are talking about a machine then I have never read or seen anything that talks or backs the theory that he used/interacted with a computer. He was alive for the invention of computers and I believe he would with people who had used computers, but keep in mind back in his day a computer was just a giant mainframe designed for automated number crunching. It was also extremely expensive and I don't believe, had he theories that required a high level of processing to calcuate potential outcomes of that theory, that he would have been given the funding for it. I would really like to know if someone has some evidence about him interacting with a computer, but from all I have read and seen this isn't the case.
Farming came before technology because we didn't hace the chips to make an computer and farming was done with horse and stiks back then.
A mainframe is just a physically very large computer, it is programmed no differently than minicomputers and microcomputers. All computers were mainframe computers before the early 1960s (because of the size of vacuum tubes and the first discrete transistors), when discrete transistors and then integrated circuits made possible the smaller minicomputers. In 1971 Intel introduced the microprocessor integrated circuit making the even smaller microcomputers possible.
the world of graphics before and after the invention of coreldraw
bell labs built one out of early point contact transistors in 1948 before the invention of the junction transistor.
In all honesty I think a job that will exist in the future but does not exist today is probably going to deal with Global Warming. A team to think of ways to prevent global warming. A solar weather man because we will be on a diffrent planet.
No, they're not. Mainframe computers are those large and bulky machines used by organizations for a specific function. They were often used as servers. Microcomputers are among the most popular form factors of computer, and modern microcomputers are much more powerful than the gigantic mainframes of the past.
Alexander Graham Bell lived his entire life and died long before the invention of the iPod.
