>>11884102you want the simple answer? they are the predecessors to multi celled organisms and sexual reproduction and are a product of chaos partially
the correct answer is that long ago god was bored and wanted to make stuff that moved. bacteriophages are the predecessors to multicelled fauna. no cell and not even counted as alive since they cant reproduce with their own kind or by themselves they held dna packets and moved with limbs that are akin to things inside your own body that move through biochemistry alone. however a small canvas only allows for so much complexity so things where scalled up and proper cells made complete with dedicated systems and sub systems
also well before that many where allowed to contribute. it was the fun phase of everything that ever was. people trying to make a better what ever. christians say god did everything but who the hell wants to do all the work. why make adam and eve when all races of man where made on the 5th day in the bible if your going to do all the grounds keeping in the garden yourself?
