Can we say that people are all evolved from trilobites?

If one day we get the DNA of trilobites, and then look at the sequence by sequencing, we can find the content that evolved with us, then we can think that trilobites used to be our ancestors.

But before that, I have reservations about it.

The reason for this is the following：

1, I checked, trilobites lived in CAMBRIAN, the time was 540-240 million years ago, and they were marine invertebrates. During this period, vertebrate fish have appeared on the earth, which can be said to be contemporaneous. Fish is our direct ancestor, and trilobites are our relatives at most.

2. "At one time, almost the whole earth was a trilobite." On the one hand, this description is not accurate, because trilobites are marine creatures, at most, they dominate the ocean. However, hegemony does not mean leaving future generations. For example, in Jurassic, dinosaurs ruled the world, and so did the number. However, at that time, our ancestor mammals appeared very early. In fact, mammals and dinosaurs were contemporary and both appeared in Triassic. It was only in the Jurassic that dinosaurs took the lead, and in the Cretaceous that we mammals gained the upper hand.
