I do think there is absolute truth.

The force of gravity and what happens when you drop a pencil. It's absolutely true that it will fall to the ground.

Also, it is absolutely true that the female body is made to create babies and it's absolute truth that it needs sperm cells to combine with the female egg. This is absolute.

Do you mean in philosophical terms such as , what is the absolute truth about murder, authority, love, spirituality, God, why we are here, etc.

IF you take a philosophy class this question will come up and it will probably covered for months and months and the discussion will still be going and going
