No living creature of any kind has been sent to Mars, not even microbes (all components of a spacecraft that will land on another body are sterilized before assembly).
No human has been on Mars yet. The only missions to Mars have been robotic, with various rovers like Curiosity and Perseverance sent by NASA to explore the planet's surface. Crewed missions to Mars are being planned for the future.

You seem to be misinformed. The first US spacecraft was Mariner 10. This was followed by Messenger. There have not been others.
curiosity
Yes, several space ships have been sent to Mars by different space agencies such as NASA, ESA, and ISRO. Some of the most notable missions include the Mars rovers like Perseverance and Curiosity, as well as orbiters like the Mars Reconnaissance Orbiter and MAVEN.
As of July 2014, no animal has been sent to Mars yet. In 2008 it was announced that Russia planned to send monkeys to Mars, but this hasn't happened yet.
