I assume that what you're referring to here is the Cambrian Explosion. It's only an explosion in geological terms--it happened over what, five million years?
More like 70 to 80 millions, estimate varies quite a bit, partly because the discovery of new older fossils extended its duration and made its limits fuzzier...
If "Science" is wrong today, and I disagree with it and say so, and am called "anti-science" for it, and then next year it is found that the "Science Experts" were wrong, for whatever reason, and the counterpoint opinion was indeed correct and scientifically accurate according to a newer understanding, then it wasn't "anti-science," but simply anti- the commonly-held scientific majority or orthodoxy of the time.
Nope. And this misunderstanding of yours is quite illustrative of your lack of comprehension of science...
Because, you see, science is not a set of knowledge, science is a method.
You are not anti-science for rejecting the current level of knowledge, you are anti-science for rejecting the very method: facts -> hypothesis -> Test of the hypothesis -> Falsification (or not) of the theory.
Now, I'm sure you will pretend to disagree. That you are all sciency... But, at the end of the day, whatever excuse you hide behind, you reject the conclusion of science because it disagrees with an immutable, revealed truth...
You already have your truth and you will not put it into question and, anything that might contradict it, is dismissed... Good for you, I guess, but that is, pretty much, the opposite of the scientific method. And, as such, justly earn you the descriptor of anti-scientific...
