Detailed explanation-1: -We now know that prokaryotes were likely the first forms of cellular life on Earth, and they existed for billions of years before plants and animals appeared. The Earth and its moon are dated at about 4.54 billion years in age.

Detailed explanation-2: -Prokaryotes are the most primitive of cells (meaning they are the oldest and simplest), and they lived at least 3.5 billion years ago. For nearly 2 billion years, prokaryotes were the only organisms on Earth. The most familiar example of prokaryotes is bacteria.

Detailed explanation-3: -The eukaryotes developed at least 2.7 billion years ago, following some 1 to 1.5 billion years of prokaryotic evolution.

Detailed explanation-4: -From an evolutionary point of view, prokaryotes preceded eukaryotes. Therefore, it can be said that prokaryotes are older than eukaryotes.
