When asking a question to creationists one might want do it on a day that is not the Lord's day because we could be in church on that day worshiping our creator.
That is actually a valid point. Although there are creationists of faiths other than yours with different holy day traditions, we all do need to be more patient. But you are here now and surely can answer the question.
It's ironic that the OP is pointing to early fossils as evidence for evolution when this sudden appearance of many animal groups with no known antecedents is the greatest single objection to the ToE.
Actually this is not true, the Cambrian explosion as it has come to be called represents a period or relatively rapid development of new varieties, but all of the new forms have antecedents that are found in the Precambrian. The precedents of mammals for example can be found in the fossil record (reptiles with mammal like features, mammals with reptile like features, etc). But no mammals are found in the Precambrian. How does creationism explain this?
We need to look at how fossils are formed. Most complete fossils are invariably linked to a catastrophe in some way in which they were buried quickly. This can be something like a flood a mudslide or landslide, a layer of volcanic ash, etc. So we see that it is possible that most fossils were formed by the great deluge which would validate the reasoning that the lower life forms would be at the bottom layers.
Yet this is not what we observe in the fossil record. It is not sorted according to size, or according to mobility, or according to the ability to swim, or according to density or the ability to float.

And when a rabbit is found in Precambrian I would expect all evolutionists to fall on their knees and ask for forgiveness to God.
When a Precambrian rabbit is found I personally will reject the theory of evolution. What would it take for you to reconsider Young Earth Creationism?
