Oh no! Another alien probe

Uhhhh, The first tree appeared in the Devonian, which is like 280 million years after snowball earth.

There were far more time elapsed between the end of the last snowball earth and the first tree with rings than had elapsed between when the first dinosaur walked the earth and now.

As far as we know, there wasn’t even multi-celluar plants right before or after the snowball earth.  Tough to grow a ring with only one cell, don’t you think?

I notice in the geologic time line that flowers are new. I always argued that birds, bee, flowers and trees must have existed at the same time. Yet, flowers are new. Plant life must have existed prior to flowers because of the existence of oil. What you say?

If my memory serves correctly the chronological order should be trees, birds, flowers then bees. Tress have been around for 380 million years or so. Birds are 150ish million years old. Flowers are 140ish million years old. And bees are a relative newcomer at less than 100 million years. Plants in general predate trees by a lot. Depending on how you define plant you could be talking about more than 3 billion years if you count cyanobacteria.
