Unix file creation time

Can anybvody tell me why unix doesn't keep file creation time? Is this such a big load for him, since it stores the modification time, the modification time and access time, but not the creation time? Is there any specific reason for this?

or through some language (any programming language) and some system calls can we get the file creation time in some way?

I believe that such information is responsible for storing the inode and, therefore, for limiting the file system itself. A quick googling search, and it turns out that the ext4 file system added storage for this file attribute to its inode.
