From SirAllen:
"Agreed. However, macro evolution fails #1, #2, #3, and #4."

(1) Observing Physical Reality
Fossils are physical realities. Matching DNA Sequences in similar organisms are physical realities. Observing baterial and viral mutations are physical realities. Now, since neither you or I live for millions of years, we will not be able to personally observe large creature speciation with our own eyes. Let me give you another example of such a phenomenon from another branch of science: The planet Neptune takes 165 years to orbit the Sun. The planet Pluto takes even longer, 249 years. I'll never see them orbit once. You'll never see them orbit once. If I can't personally observe it because I don't live long enough, I should dismiss it as not possible? Heck, Pluto was not even discovered until 1930, so we have only really "seen" it going around for 75 years. How can we be sure it will continue for the next 174 years?

(2) Forming theories based on observations
I fail to understand how you think the theory of evolution fails on this point. Just some of the observations are listed in my reply to point one above, and other posters have done yeoman's work illustrating others in great depth.

(3) Constructing experiments to test theories from Step 2
Failing to get ahold of Doc Brown's "flux capaciter" to build a time machine, experiments on evolutionary theory have been largely conducted at the biochemical level. Tracing retroviral DNA sequences to determine species divergence for example. Such experimentation exists, is published and peer reviewed, and is largely available for you to look up on this here Internet.

(4) Take the results of the experiments are repeat from Step 1 as long as a better understanding is desired
Again, the published material referred to above shows that indeed Step 4 is taking place.
