Pre-Flood Earth: Speaking of "Giants"

There were giants in the earth in those days... Genesis 6:4

"Earth was covered with giant insects. Imagine a world where dragonflies are the size of crows and millipedes are as long as cars.
The planet’s landmasses were beginning to form the supercontinent of Pangea. Extensive swamps and warm, humid forests dominated the landscape. And giant insects weren’t the only huge creatures roaming the planet. There was also a vast array of marine life, like early forms of sharks and a giant amphibian that would reach up to 6 feet long

Now, the first thing you’ll probably notice would be the giant insect like creatures. One of the most iconic was the meganeura. This insect resembled a modern-day dragonfly, except with a major twist. It had a wingspan of up to 30 in. Scarier than that, it was carnivorous, hunting down other insects and small amphibians.

So, that thing is in the sky, but on land, you’ll have the arthropleura. This millipede-like creature could grow up to 8 ft. long.

Another creepy-looking insect was the pulmonoscorpius. This was a giant scorpion that mostly roamed the swampier areas of Earth. They could grow 28 in. long. There were also giant cockroaches that grew to 4 in. and mayflies with 18 in. wingspans."
