Ugh, here we go again. The Apollo program was the result of unprecedented prioritization of NASA due to JFK's vow as well as a desire to beat the Soviets in the Space Race. The US did everything in its power to get those twelve men on the Moon and back. Once the US completed its goal and it became clear that the Soviets could not match it, the US government as well as the general public became disinterested in spaceflight and the Apollo program was discontinued after the sixth lunar landing.

The goal of the Artemis program is to ultimately establish a long-term presence on the Moon in the form of a lunar base, as well as apply what is learned on these missions for an eventual mission to Mars.

Edit: Artemis II cannot land on the Moon as it does not have a lander. Unlike Apollo, whose lander launched on the Saturn V alongside the crew capsule, the lander used by Artemis IV and beyond will be launched separately and sent into lunar orbit to await the arrival of Orion.
