Explanation:

James Hutton and Charles Lyell, in the context of geological studies (related to Earth's age), proposed that Earth is millions of years old. Their work in geology (a subfield of Natural Science, specifically related to Earth's history) supports this, as the concept of deep time in geology aligns with Earth being millions of years old, not thousands, hundreds, or trillions (trillions is too extreme for current scientific consensus on Earth's age, and thousands/hundreds are too young).

Answer:

millions
