Damian says, "We have been here for Days!" - You don't need a capital D in "days."
"'Do something!' He cried." It should be a small h in "he."
"'Miss!' He said again." - It should be a small h in "he."

When you write "landborn" just check how you've written it because, once or twice, you write"land-born" and "land born" instead.
"'And easier to guess where your mind is.' Teased Jetta ..." - It should be, "... where your mind is,' teased Jetta."
Similarly, "'I would marry a land born before I would marry a Sunner.' Declared Jetta." - It should be a comma followed by a small letter.
"It seems like people are being sent to the Trench all the time anymore." - "Anymore" isn't the right word here. Unless you mean they are not being sent to the Trench all the time? If not, I would switch that word for something like, "these days."
" She did not want me to burden you with this much information before . before." - The period and extra spaces aren't quite right here. I would change it too something like, "before, before ..." A comma, then ellipses at the end would work well.

"... turned to Paul, leaning on his shovel watching, and said ..." - I would put a comma after "shovel" because it is Paul who is watching, not the shovel.

"Whenever a person wanted a comfortable to be, this desk was recommended the most." - I wasn't sure what this meant. I wondered if you meant, "Whenever a person wanted to be comfortable"?
"Sounds like you need a caring object to reach out to". "I'm all ears." - You don't need two speech marks here. Also, the period is outside of the first speech mark.
"She was afraid someone would do dome harm to her." I'm not sure what "dome" means here. Maybe, it's a typo?
"Melody was more than py to arrange a meeting for them. - I think you mean "happy" here?

"The pair stood silently as if they were in the presence of some diety ..." It should be "deity."
"“Raising a happy child,” she read the faded title before she tentatively opened the pages ..." This should be a full stop at the end of the speech and then a capital S.

I just have one point in this sentence:The last message from him was by radio to my grandmother a few years later. "He said, 'I found it.' - You don't need the quotation mark before He said ... because those words are still Parker's words.

"She was alive when they ambulance left so..." - It should be "the ambulance."
"my boss started at me dumbfounded." - I think you mean "stared."
"I slowly wander back to my office" - It should be "wandered, past tense.
A general thing I would suggest is to not include so many ellipses. These punctuation marks should be used sparingly in creative writing. There were some times where they made me read the meanings of your words incorrectly.

Specifically: "Walking down a long constantly curving corridor, Lemmok and Pavicca nob as two different Alien races" - I didn't understand what "nob" means in this context. It brought me out of the story, trying to figure out its meaning.
More generally, you use the word "that" a number of times when "the" would have been more appropriate. For example, "Lemmok got up and escorted that female crewmember to the entrance into that small room." It would be better to say "the female crew member" and "the small room." Or, even better, to give them both a little description.

"He had a military bearing and stood straight, His eyes ..." - It should be a full stop after "straight," not a comma.

"'And DON'T try simply asking her,' Dad was saying." - I would say "Dad said." It is more active and less passive.
"Mom had carefully extracted one, two, three ... fortunes out of their respective cookies." - I'm not sure about the use of ellipses here. If you wanted to play on the word "fortunes" I would italicise it, and not use the ellipses.

"A second before Rachel Grant found herself standing alone on a cool, shady mountain side in an evergreen forest; she’d been ..." - This should be a comma, not a semi colon.
"A short hike up to the trail’s crest, presented Rachel ..." - The comma isn't needed here.
"The amphitheater appeared to have exits like the Chicago Cub’s ballpark." - I could be wrong here, but I think the club is called Chicago Cubs, right? Not Chicago Cub? Assuming it is, the apostrophe should be after the s.
"Rachel interrupted him, 'who’s we?'” - It should be a capital W here at the start of the dialogue.
"Thank you for your incite." - It should be "insight" because "incite" means to call people to do something (usually riotous)

"Unconsciously peeling off her wetsuit ..." - I don't think unconsciously is the right word because the means literally being unconscious, which Serena isn't. Maybe, "distractedly" or "subconsciously" would work better?

" ...waves lost their energy and he would paddle out once more. " - I would put a comma after energy because, "and he would paddle out once more" is a separate clause.

Just watch your new paragraph spacing because you haven't double-spaced it in some places.

The last paragraph is all in italics, and I can't work out if you've done that on purpose, or if it is a mistake. I don't think it is an internal thought, so I can't see why it should be italics. But I'm open to being wrong.

In general, watch your use of semicolons. These should be used sparingly in fiction, and there are only certain circumstances where they are technically the right punctuation to use.
"'You might say, I may be overweight, but, this means that I have more love to give, I have expanded my horizons' Ha! Ha! I can choose to be a mare or a colt, but, whichever I choose, I have a mane and a tail; the mane guides me to the main pathway." - A couple of things here. You need to have some form of punctuation when you close speech marks. Secondly, I'm not sure why you have closed the speech marks, then continued with the speech but with no speech marks. You do this in a couple of places, and it makes the text a little bumpy to read.
"It was now time for Mrs. Whitmire's next project. She wants the class to be creative." - You have switched tense from past to present. I would just check the rest of the story for places where you have done this. It is easily fixed.
"'If people wouldn't be so angry at each other, then the temperature would cool down. Their anger was red hot ..." - Firstly, you haven't closed the speech marks after down. But, more importantly, who is they? It is uncelear to whom you are referring and, again, brings the reader out of the story.
