Why do most scientist reject Lovelock's third statement about Gaia?

Most scientists reject Lovelock's third statement about Gaia, which suggests that the Earth system regulates itself to maintain conditions favorable for life, due to a lack of empirical evidence supporting the idea of a self-regulating planetary system. Critics argue that while ecosystems exhibit resilience and can adapt to changes, they do not possess the intentionality or goal-directedness implied by the Gaia hypothesis. Furthermore, many scientists emphasize the importance of understanding complex interactions within biological and physical systems without attributing them to a singular, overarching regulatory mechanism.
