It was not "instead of", he was doing both.
It is just that Japan surrendered in August 1945 after the second atomic bomb (of 23 planned atomic bombs before the end of 1945) instead of waiting for the invasion to begin in November 1945. It took time to set up the men, weapons, and supplies for the two planned invasions (November 1945 and spring 1946) while the atomic bombs were ready to use starting on August 6, 1945.

Two atomic bombs were dropped on Hiroshima and Nagasaki Japan, because Japan would not surrender, and dropping atomic bombs was considered better than invading the country. After the bombs were dropped, the war ended, and the world has had to deal with the threat of nuclear war since 1945.
To end the war quickly so the U.S. did not have to invade Japan with a huge amount of Infantry soldiers and to spare the lives of very many invading U.S. soldiers.
The same day they were ready Truman had the decision. The people were ok with it.
