You can control the pixel size of an image by setting the scale parameter of ee.Image.reproject():
// Reference a Landsat scene.
var image_30m = ee.Image('LANDSAT/LC08/C01/T1/LC08_044034_20170614');
// Define visualization parameters for a true color image.
var vizParams = {'bands': 'B4,B3,B2',
'min': 5000,
'max': 30000,
'gamma': 1.6};
Map.addLayer(image_30m, vizParams, 'image_30m');
// Get the projection information for a band.
var band2 = image_30m.select('B2');
print('CRS:', band2.projection().crs());
// Display a bilinear resampled image with 10m pixel spacing.
var image_10m = image_30m.resample('bilinear').reproject({
crs: band2.projection().crs(),
scale: 10
});
Map.addLayer(image_10m, vizParams, 'image_10m');
If you want even more control over the projection, you can manually change the CRS transform (crsTransform) parameter:
// Reference a Landsat scene.
var image_30m = ee.Image('LANDSAT/LC08/C01/T1/LC08_044034_20170614');
// Define visualization parameters for a true color image.
var vizParams = {'bands': 'B4,B3,B2',
'min': 5000,
'max': 30000,
'gamma': 1.6};
Map.addLayer(image_30m, vizParams, 'image_30m');
// Get the projection information for a band.
var band2 = image_30m.select('B2');
var proj = band2.projection().getInfo();
print('CRS:', proj.crs);
print('original CRS transform:', proj.transform);
// Construct a new CRS transform, using 10m spacing.
var transform_new = [
10,
proj.transform[1],
proj.transform[2],
proj.transform[3],
-10,
proj.transform[5],
];
print('new CRS transform:', transform_new);
// Display a bilinear resampled image with 10m pixel spacing.
var image_10m = image_30m.resample('bilinear').reproject(
{
crs: proj.crs,
crsTransform: transform_new
});
Map.addLayer(image_10m, vizParams, 'image_10m');

I'm sorry, but historical Google Earth images are not publicly available. There is some imagery in Earth Engine that is higher resolution than Sentinel2. You might want to take a look at these datasets to start:
https://developers.google.com/earth-engine/datasets/tags/skysat?hl=en
You may want to save out your results from Earth Engine and then load them into Google Earth. If so, this may help - https://developers.google.com/earth-engine/guides/exporting#exporting-maps
