I doubt it too.
Today I observed a small child, who was fascinated with a pool of water at the park. It had recently stopped raining and the child, wearing yellow footwear was stepping in the puddles and smiling. His parent was communicating on her cellular device and only paying token attention to the youngster. As she walked slowly around, her silken scarf had fallen onto the ground. The child noticed and picked it up, offering it to his mother, who was too engrossed in her conversation to attend to him. After waiting a moment he took the scarf back to the small pool of water and began to trail it into the water At first he only dipped a small portion in but increasingly he dipped more, always looking back at his mother to see if she were watching. At last he had it full in the water and the colours, which must not have been fast, were spreading from the scarf out into the pool. The child was delighted and ran to his mother, who had just ended her conversation. She reached for her scarf but not finding it looked around, only to see the child gesticulating and saying "Pretty!". She flew into a rage, berating the child for getting her scarf all dirty and calling him a "bad boy". The child was at first confused and then he began to cry. The mother grabbed the boy up roughly and left the park, muttering insults and threats to the crying child.
I realize that I am only supposed to represent facts/observations in these reports, Commander, yet I feel compelled to make commentary here. Before this mission, I could not understand why we had not disclosed our presence to the Earthlings. Having seen first hand how cruel they can be even within their own tribes, I fully understand the reluctance of the Guardianship to proceed with public overtures to Earthlings. They do not truly understand love or friendship for the most part. There may be exceptions to this rule but they are not the majority. We would be in grave danger of being destroyed if we were to officially make our presence known. This is a most backward species.

It's not that there isn't perhaps life on other planets. It's that, given the state of things, why would they come here and talk to us?
