My mother language is Tamil (which considered to be a very old language). While creating Russian language did they got any words or characters from Tamil language?
Obviously nobody created the Russian language, it evolved from Slavic which evolved from some proto-Slavic which evolved from something that we now call Proto-Indo-European language.
Tamil is not PIE language, it belongs to a widely recognized Dravidian family. It's an open issue how this family is related to the PIE but definitely the answer to your question is - no, there's not the slightest hint of Tamil influence on Russian.
The most famous word borrowed from Tamil is
катамаран - I guess it's the only relatively widely used Tamil word which is used for describing something not specific for Tamil-only context.
