I am quite new to GIS so I am sorry for my "primitive" vocabulary.
In QGIS, I have a set of points falling in specific coordinates in Africa and Europe.
I would like to select only those points which are within the continents (thus not in the sea).
Probably the figure is more explanative :
I have tried to use the intersection feature but it is not working as the only result I am obtaining is the only point which is actually falling perfectly onto a line (see image. I have made the point bigger just to visualize it better).
Can you help me with this?

It seem that your "land" layer is only line (ie there is no inside so nothing to intersect) you need to either polygonise your layer or find a layer that is already made of polygon. With point and polygon you then can use the "select by location" tool in the processing toolbox

Ok I was able to solve the issue and select all the points falling within Europe.
What I did was first to select all the european countries "touched" by the points and create a new shapefile. Then I have used again the "select by location" tool to take all the points within the selected countruies. Probably not the fastest solution but it worked. Thank you everybody

Export the Europe shapefile (Right click on the layer - Export) to CRS:4326. After use the Geoprocessing Tools / Clip algorithm. As input, use your point layer, and the polygon layer as clip layer.
I have tried your soulution but I have an error when running the clip. It says (I am translating from Italian): "the element (2) has a not valid geometry. Correct the geometry or change processing settings in "ignore not valid input geometries""

Hmm, there is a geometric problem with the Europe layer, maybe comes from the multipolygons. Explode the multpart polygons with the following method: Vector / Geometry Tools / Multipart to singleparts
