No they weren't. It wasn't until the late 19th century that they suggested that the Earth could be older than 10 000 years old based on one guy noticing different layers of rock. He believed that such layers must have taken a long time to come out of the ground. He used mathematics to determine that the Earth could be millions of years old. He did not say billions.
