The current best estimate for the age of the universe is 13.75 billion years. The first trees are thought to date from the Carboniferous, approximately 359 - 299 million years ago.
As such, 400 billion years ago (roughly 1300 times older than the estimated point when trees first appeared on Earth and approximately 23 times older than the age of the universe) it is VERY unlikely that there were any trees at all.

Does the Milky Way have 400 billion stars?
Yes, the estimated number of stars in the Milky Way galaxy is around 100 billion to 400 billion, with recent research suggesting it could be towards the higher end of that range.
What is the farthest galaxy ever observed by Hubble?
The farthest galaxy ever observed by the Hubble Space Telescope is GN-z11, located about 13.4 billion light-years away. This means we are seeing the galaxy as it was just 400 million years after the Big Bang.
How many solar systems in our galaxy?
Our galaxy, the Milky Way, is estimated to contain between 100 billion and 400 billion stars, many of which likely have their own solar systems. Current estimates suggest that there could be over 100 billion planets in the Milky Way, indicating that there are potentially billions of solar systems. However, exact numbers are difficult to determine due to the vastness and complexity of our galaxy.
How long did Montserrat last for?
it was dormant for 400 years before it erupted.
Is it true that in the milky way theres more than 600 billion stars?
We don't know with any precision how many stars are part of the Milky Way galaxy. Case in point; scientists announced just last month that they have discovered a brown dwarf star only 10 light years away. Every time our telescopes get better, we discover more and more dim stars; 600 billion may actually be on the low end of how many stars there are in our galaxy. So I'd say that this is true.
Approximately how many trees are their on your globe?

Approximately how many trees are there on your globe?

How many times does sixteen go into 400 billion?
Well, 4 divided by 16 is 1/4, so 16 into 400 billion it must be 100 billion times that. That makes it 25 billion. Or if you like, 400 divided by 16 is 25, leading to the same answer.
How long is 4 billion years in decades?
A decade equals 10 years, so to convert 4 billion years to decades, simply divide by 10.4,000,000,000 years / (10 years/ decade) = 400,000,000 decades.So 4 billion years is 400 million decades
