I can't find OpenLayers Plugin to install in QGIS 3.6.
I want to open Google Earth in order to add coordinates and open satellite image to start mapping.
Instead of using OpenLayersPlugin (which, as already mentioned, causes trouble sometimes and is experimental) I recommend to directly add XYZ Tiles of Google to QGIS:
The connection is saved. So once you created it, it will be available on your PC, no need to reconnect every time.
Here is a list of possible Google URLs:

if you want to use OpenLayersPlugin check experimental flag under settings (like @Joseph pointed out):
If you want to use QuickMapServices then load the plugin and go to settings and then to the More services Tab and Click the "Get contributed pack"
You can also use XYZ tiles. In this video https://www.youtube.com/watch?v=M-WfXHbGOlw&t=1s Klas Karlson explains how to load them. In the description of the video you have a a link for the python script, and you will have a lot of base maps that you can use. XYZ tiles are available in the browser pannel. If you do not see the browser pannel, go to view/pannels and activate browser. Check the video and give it a try

. However, it is highly recommended to instead use the QuickMapServices plugin as this contains many more maps and is frequently updated.
