It is the theme of many world religions that the human being arrives upon this earth somehow flawed, imperfect, or broken, or becomes so early in life, and that the purpose of the human's mundane existence is to work toward perfecting itself.
In your belief, what is broken and needs fixing? What must you do to go about fixing and perfecting yourself and/or others? To what end?
Nice. However, it is the theme of many persons that human beings arrives upon this earth because of them. Without them, there would be no 'little' human beings, they say.
Flawed? Probably. Why? Because those 'persons' who 'made' the little ones can be the first ones to admit that they are not Perfect, not not flawed in any way.
Those that study UFO and outer life forms believe that they could be 'little' ones of theirs rather than 'little' ones of the 'persons'.
To persons and humans, this concept is flawed. To the 'little' ones of the outer space forms, they ask for explanation.
Asking for explanations is their way. For humans and persons, seeking is theirs.
Humans and persons are 'homo-sapiens'; or 'wise person'. Although they, outer life forms, are more advanced in technology of sorts, they still lack in knowledge.
And it makes sense. Their 'world' is one of 'material'. There is probably very little 'nature' that lives outside of theirselves. And so for them to live in that 'world', they rely more on the 'materials' needed to sustain more than being part of the larger 'nature/life' which is on Earth.
So if you were to tell them that 'nature' and other lifes on Earth 'matter', they might wonder and ask what is meant by that and ask why 'they' would matter.
And so we can draw the analogy of their material needed for sustenance to Earth's nature and other lifes for the same, our sustenance.
And if they like 'life', they will probably understand.
