Because if you have the pedals stuck to the wheel axle, and no gearing inbetween, the only way to get some useful speed out of the bike is to have a really large wheel.
Because before the chain drive and gearing was invented, bikes were direct drive - meaning that the drive wheel spun at the same rate as the pedals. The only way to get some speed out of the bike then was to make the drive wheel really big.
Once the chain drive made it easy to add a gearing ratio wheels could be built with equally sized wheels and a better rider position.

Why spokes are used in wheels?
Because before the days of big milling machines and huge lumps of aluminum the most available way of making wheels that were true, strong and reasonably light was by using spokes to lace a rim to a hub. For bicycles, with their relatively large diameter and lightly loaded wheels, the method is still competitive.
