Hi Rye,
"I have set the GEOGRAPHICLOCATION with WORLD-MERCATOR (WGS84) GIS Coordinate System..."
Don't use GEOGRAPHICLOCATION. That command is meant for vanilla autocad, and it has unpredictable results in Civil 3D. Use instead MAPCSASSIGN, MAPCSLIBRARY, or Drawing Settings.
Screen shots might shed some light on the problem.

<<…it shows the correct location…..but the objects, labels, and polygons do not reflect to the map…>>
Hmmm, that’s confusing. If it shows the correct location why doesn’t it reflect the to the map? What does ‘reflect to the map’ mean? Would it be possible to re-describe your issue?
Can you also upload an image of the Google Earth that shows where your linework lands?
Your willingness to share will go a long way in diagnosing your problem. Congrats landing your internship!

@Pointdump I tried doing MAPCSASSIGN but it no longer zooms into the desired coordinates and the objects are still not present. When exporting to kmz, I selected "All objects" and followed the geo-reference, I also ignored the nudge settings.
You, or the original author, didn't give the drawing a proper coordinate system. Here's a one-minute crash course to diagnose whether you, or the original author, drew the line work at the correct geospatial location.
- Open the original drawing then select and COPY all objects to Clipboard making sure to use 0,0 as the BASEPOINT.
- Open a brand new, clean drawing. (Use your standard office template OR use a plain out-of-the-box version.)
- Using MAPCSASSIGN command, assign EPSG 3857. (Image-1)
- Right-click anywhere in modelspace and PASTE the contents of you clipboard. Use 0,0 as the insertion point.
- Go to Geolocation Tab=>Online Map Panel=>change Map Off to Bing Hybrid. (Image-2) (Bing logo will appear in lower right corner of modelspace when connected to the Bing Map server.)
- Zoom extents to see your linework.
If your linework is consistent with Bing Hybrid imagery, then your drawing is properly georeferenced. If not, there are two possibilities, one of them, we don't know which one, is the correct diagnosis.
- The drawing is NOT using WGS84 EPSG 3857 as the assigned coordinate system, it's using something else. This means someone turned off (deactivated) the assigned coordinate system and you need to figure out the exact one he used AND reactivate it using MAPCSASSIGN command. This will enable you to perform the export procedure correctly.
- The drawing was never georeferenced to begin with, meaning it was haphazardly drawn in any ol' spot in modelspace. Unfortunately, you now need to assign an appropriate coordinate system to modelspace AND physically (a) move, (b) scale, and (c) rotate all objects to their correct geospatial location. You may have to do a combination of a, b, c, or do all three. The coordinate system you will assign to the drawing cannot be determined unless you are more forthcoming and provide more info.
Uploading the actual drawing will facilitate a fast and accurate solution.
If you can't upload the drawing itself, you may draw a square/rectangle surrounding your site. Make the four sides tight around the linework. Next, delete ALL objects inside the square/rectangle. Do not delete the rectangle! Perform a SAVE AS on this drawing giving it a new name so it's distinguishable from the original. Upload this new drawing to the Forum and be sure to disclose the city, state of the site.

Rye,
In addition to excellent advice from @ChicagoLooper, attached please find a shapefile, drawing, and KMZ of Vicente Hizon Sr, just to show that exporting to KMZ does work.
Please post your drawing. (If it's allowed. Ask first)

Panabo, correct?
Can you describe the object you want to export.
Are they Civil objects? Alignments, cogo points?
Are they points? Blocks?
Are the Lines? Polylines?
Are they closed polylines?
Are the labels mtext? Mleaders? Or do you have Object Data?
The export to KMZ function in civil3D Toolspace is weak. Since you're running C3D, you also have the Map3D toolset as seen in the Planning and Analysis workspace. Map3D's export function is much more powerful but how you use it depends on the questions above. And how your label data is stored makes a big difference in how it's displayed in Google Earth. Huuuge difference!
If you don't need to export any civil objects then I'd suggest you export 3 times: the first for points/blocks, second for lines, and the third for closed polygons. When you import them into Google Earth, you'll have all the data you want. Yes, all 3 exports will be the same--each is exporting a different 'class' of objects.
From what you're describing, exporting all classes at the same time using Civil's feature named Export KML is weak and can't handle your type of export.

Using Map3D's MAPEXPORT command you can export to shapefile format. Although I can select only a portion of the DATA I need, MAPEXPORT can also grab ALL THE KML DATA whether I need it or not. The Export to KML on C3D's Toolbox Tab doesn't give options to select specific data.
Google Earth is capable of importing more than just KML/KMZ, it can also import SHP format. If I export DATA along with the linework, then the lines in Google Earth can display data. For example, clicking on a street while in Google Earth will reveal the street name.
If the AutoCAD linework is storing data, then an exported shapefile can export the data too. Then when the importing program 'reads' the shapefile it will also retrieve the data. The KEY to this exercise is DATA, how it's stored and how it's retrieved.
