Biogenesis is the idea that living things come from other living things.

decomposition
yes, that is called cell therory. All living things come from other living things.
I believe it is called genetic engineering.
Currently this is not true - all living things on Earth at this time were created by other living things through either asexual or sexual reproduction. However, prior to the formation of life on the planet, it is hypothesized that abiogenesis took place to create living organisms from non-living materials.

No one created diseases. Diseases start existing inside of other living things on their own.
