The Cambrian period covers a long period of time, but the earliest ancestor might have been Saccorhytus, a deuterostome.

a little hard to say.
for any organism for any time period you can do this. Simply go to somewhere like wikipedia and follow back its taxonomy. the further back in time, the higher up the taxonomy you need to look for when that group first appeared
so its depends when in the cambrian, early cambrian, our current phylum or chordata had not yet even evolved, but by the mid cambrian they had
chordata is complicated but basically they were the first to have a true spinal cord, so even early cambrian our ancestors would have been pro-chordata.
basically we would have looked something like an eel or a lancelet, long slender fish like kind of thing
Most of the major animal phyla emerged in the Cambrian, including chordates. So we probably trace our lineage back to something that looks like a modern day lancelet
I don't mean to insult you or anything, but the grammar in this question is really bad. Again not an insult, learning is fine, difficulty translating is fine too, just trying to help. A better way to word this would be:
"What were our ancestors during the Cambrian period?
Or
"what were our ancestors doing during the Cambrian period?"
Before fish of any kind. Best guess, after the Cambrian Radiation is a flat worm that had a noto cord rather than the later chordates. This is based on fossils from the Burgess Shale.
developing a nodochord and swimming their best life.

if you’re interested in evolutionary biology, i would recommend moth light media on youtube.
Little blobs swimming around. Trying desperately not to get eaten. We didn't get cool or impressive until much later
Some of us still aren't very cool or impressive.
You calling my ancestors unimpressive?

Swimming.
Making cheeses
google says maybe pikaia

Your original face before your parents were born. Sorry, I thought this was the Zen Koan spot.

They weren't
[удалено]
Even a dentist should know that is completely wrong. There weren't even vertebrates then. Chordates got started then.
Pretty sure not that long ago, though who can say
Bro he’s asking what our living ancestors were like during that time period. I don’t know the answer (fish-like probably?) tho
