i'd really like to know how they know the age of this "creature"

Im pretty sure by measuring it's size. Since they know the average growth rate, they can calculate back.

I can't think of any other reason that a person would be all worked up over the presumed age of seeweed, so im making the wild guess you are a young earth creationist.

Unfortunately for you, at 8000 meters in length, even if the dating was off with a few 10.000's years it's still gonna be way more than 6000. There are physical limitations to how fast seaweed can grow after all.

I can't imagine it growing a meter per year. The growth rate for other members of this species is between 3 to 10 cm per year.

Any way, if it was like a super fast growing mutant, we would find out soon enough cause it would continue to grow 1 meter per year... right?

how large was it when the Lord made it in the first place?

"I can't imagine it growing a meter per year. The growth rate for other members of this species is between 3 to 10 cm per year. "

Bamboo can grow up to 3 feet a day.

It would be nice if they measured it's current growth rate before calculating an age. I bet it's more than "other members of this species". But there's no guarantee that the current growth rate represents this plant's past history either.
