Final answer:
The Pioneer and Voyager spacecraft do indeed carry a message from Earth in the form of plaques, audio, and video records.
Step-by-step explanation:
The statement is true. The Pioneer and Voyager spacecraft do indeed carry a message from Earth. Each Pioneer spacecraft carries a plaque with a pictorial message engraved on a gold-anodized aluminum plate. The Voyager spacecraft, launched in 1977, has audio and video records attached, including over 100 photographs and a selection of music from around the world. While it is very unlikely that these messages will ever be received by an alien civilization, they serve as a symbolic representation of humanity and our desire to communicate with other beings in the universe.
