Dear Aliens,
I'm Mary from Earth. Humans have made great achievements in space exploration. We sent satellites into space, walked on the moon, and built space stations. We also use telescopes to study distant stars.
We are friendly and want to communicate with you. We hope to learn about your world and share our culture. Maybe we can help each other in the future.
Looking forward to your reply.
