Once continents formed around 3.5 billion years ago, complex life on land was ready to flourish.

Explanation:
Land life didn’t appear on the newly formed continents right away. Around 3.5 billion years ago, crust existed, but soils, stable climates, and enough atmospheric oxygen for complex organisms weren't in place. Life at that time was primarily microscopic and confined to the oceans. It wasn’t until hundreds of millions of years later that true land plants evolved, followed by land animals, enabling complex ecosystems on land to flourish. So, the statement is false.
