When you say you don't believe in "macro-evolution", what exactly do you mean? "Macro-evolution" is not a separate process from "micro-evolution", they are identical processes observed on different timescales.
Genetic variation coupled with limited resources leads to some traits being more beneficial to survival than others. Individuals with beneficial traits pass on those traits to their offspring, while those with detrimental traits do not survive to reproduce. This process leads to small changes on short timescales, and accumulates to result in large changes when given a long time to act.
In order for micro- and macro-evolution to be separate processes, you would need two separate types of genetic material: one shared between all organisms and one which is specific to each organism. But this isn't what we observe - genetics works in much the same way across all life, and genetic material can be fairly trivially transferred from one organism to another.
I guess I'm trying to say that I don't believe that over billions of years a single-celled organism could evolve into a human being. I believe evolution works on a much slower time scale. I guess this is what I mean rather than "macro" or "micro."
