Wrong, macro evolution has been observed.
I would like you to define "chemical evolution" before I make any other corrections.
i think it would be beneficial for you to define what you believe macro evolution is and how it has been observed.
the scientific community, last i checked, had taken the stance that the difference between macro evolution and micro evolution, is essentially time.
if you wade through the argument the idea is that adaptation on a genetic level can eventually develop into speciation.
the problem is that no direct change into a wholly new species has been observed, or recreated.
genetic drift does not correlate to new genetic material.
the real problem that occurs with what evolutionary proponents claim as examples of macro evolution, is the amount of time they require for the event to transpire.
millions of years being the minimum. billions of years if you want to talk about a single celled organism becoming a modern mammal.
this requires them to first prove the earth is at least millions of years old.
i have read through dozens of young earth creationist arguments that evolutionary scientists claim to have rebutted (although often it is merely that they have managed a rational counter claim that bears no more plausibility than the claim they attempt to undermine)
but one glaring irony seems to pose itself. what argument exists that the universe is billions of years old?
cosmochronology?
its based entirely off of speculation.
biostratigraphy? its a chicken and egg issue, how old is the fossil, well because its in this layer of strata, its 5 million years old. oh well how do we know that everything in this layer of the earth is 5 million years old?well you see, we found this fossil in there that went extinct 5 million years ago.
carbon dating has long since been abandoned by evolutionary scientists because its been proven useless. so now we have a dozen other ways to infer the age of fossils that all rely on pure assumption, and have no more hope of proving accurate than carbon dating did.
yet this did not stop evolutionary scientists from touting carbon dating as inarguable fact for decades.
the fallacy of these claims as to the age of the earth is that no means of measurement can be known valid, because no observation of their means of dating have lasted longer than a handful of decades.
evolution requires more faith than i have. because it requires consent to the validity of a series of assumptions that are constantly changing.
and every time their means of inferring proof are found out to be impossible, they simply fill the void with the next generation of new scientific assumption.
the problem people should really look at, is that evolutionary scientists try to make the math and science fit their theory.
instead of allowing the scientific data that's available to speak for itself.
science is meant to be unbiased. that's why it has to be observable and predictable.
