The Camberian explosion has established more than 60 different phyla. This means tens of thousands of species that exploded into life fully formed.
I'm not sure where you got this misconception. The Cambrian explosion constitutes less than 25 different phyla, which together represent only 1500 different species known to exist in the Cambrian time period.
No "60 plyla", no "tens of thousands of species." The Cambrian "explosion" was merely the development of a few phyla containing a few hundred species each. That diversity expanded over time to the billions of species we observe today.
If you say the Camberian explosion is invalid, how can 60 phyla emerge in a very short time period (geologically speaking) and fully formed and independent of each other with no evolutionary ancestral species?
It's not that they had no ancestral species; obviously they must have had ancestors. They simply had ancestors that could not easily fossilize - the Cambrian is the earliest time that we see hard-shelled organisms.
I doubt that you have family records dating beyond a few generations. Certainly you don't have a photograph of any of your family members from before, say, 1800. Are we supposed to conclude that none of your ancestors before 1800 had faces? That the Mr.Matrix family springs into existence "fully formed" sometime after 1800?
Or, knowing that organisms are almost always born of other organisms, isn't it much more reasonable to simply conclude that you have ancestors that we simply don't know anything about?
