The contention that if X is the progenitor of Y, then X must be more complex than Y is simply not true. There are many examples that disprove this contention, but one that is easily checked out on many web sites is the Mandelbrot set. This set is generated by the vary simple iterative sequence: Z(n)
good show however if you think hard about this you'd see this assertion of yours can be used show how a god is not needed and that complexity doesn't require design. It amuses me to an extent that you would fail to see this then I realized you're coming at this topic from the stand point "god does exist" rather then "does god exist?" . I can see how you can easily over look that.
this infinite regression can exist in a finite span of space, and/or time if it converges to a limit.
does it? is everything finite? Why would anyone assume time converges to a limit or for that matter is linear?
